In 1901, Valdimar Ásmundsson published Makt Myrkanna (or Powers of Darkness), an Icelandic translation of Bram Stoker's popular gothic novel, Dracula. Stoker approved of the translation, collaborating with Ásmundsson on his efforts and providing an author's note to appear in the original edition. In 2014, Hans De Roos set out to translate Ásmundsson's Icelandic tale back into English--and was astonished to find that Powers of Darkness was not merely a translation of Stoker's classic novel, but rather an entirely new adaptation of the story. Large swaths of Stoker's original text had been removed or modified, resulting in a tightened version of Dracula that more fully drives home the terror of the infamous monster.

Powers of Darkness follows Stoker's original outline in many ways, using Harker's journal entries to convey the terrors of Count Dracula's castle, and following a similar timeline and cast of characters. But Stoker and Ásmundsson's adaptation draws heavily on both Norse mythology and aspects of the Icelandic language as well, changing the original story in subtle and fascinating ways. These alterations are expertly highlighted throughout the text in De Roos's detailed and explicit annotations, which provide linguistic, cultural and historical context for the revisions made to the original Dracula. With a foreword by Dacre Stoker, a descendant of Bram, and an afterword by Dracula expert John Edgar Browning, Powers of Darkness is a delight to read as a classic tale of horror and fear, and as a fascinating look at the role of translation in the interpretation and understanding of classic literature. --Kerry McHugh, blogger at Entomology of a Bookworm

Sara Flannery Murphy's debut novel, The Possessions, resists easy genre classification. The protagonist, Eurydice, a shy young woman with a troubled past, works as a "body" for the Elysian Society. Her job involves channeling dead wives, daughters and girlfriends for their grieving loved ones by taking a pill called a "lotus." Eurydice's life is one of routine and numb efficiency, interrupted by a new client, Patrick Braddock, who forges a more intimate connection with her as she channels his deceased wife, Sylvia.

Outside of the imaginative premise, though, The Possessions is surprisingly grounded. There are few futuristic or otherworldly touches aside from the lotus, and Murphy dispenses with the dense world building common to science fiction. Patrick Braddock's seemingly idyllic relationship with Sylvia soon reveals itself to be more complicated as Eurydice starts playing amateur sleuth and learns more about the circumstances surrounding Sylvia's unusual death.

The Possessions is essentially a psychological thriller with a science fiction twist. Numerous mysteries weave in and out of the main plot, adding a page-turning element to the book, and another ingredient to Murphy's intriguing genre fusion. The more questions are answered, the more fragile Eurydice's identity seems to become. When she starts to confuse Sylvia's thoughts and emotions for her own, The Possessions raises the terrifying possibility that Eurydice might be permanently displaced from her "placeholder" life. Murphy's debut novel mixes these intellectual fears with more down-to-earth threats, resolving its mysteries in shocking and thoughtful ways. The Possessions is difficult to classify but very easy to enjoy. --Hank Stephenson, bookseller, Flyleaf Books

Chris Ewan (Safe House) has wrought more hairpin twists and turns than a mountain road in the adrenaline-spiked thriller Long Time Lost.

Widower Nick Miller lives a covert life protecting compromised witnesses from a ruthless British crime family. When Miller falls hard for his latest charge, Kate Sutherland, his carefully managed program begins to disintegrate, threatening to expose every witness he's helped, as well as his own dark secrets.

Ewan, channeling his inner Robert Ludlum, wheels his characters across various European locales to great dramatic effect. What begins as a botched hit on the Isle of Man becomes an ever-tightening game of cat-and-mouse in Rome, Prague and the Swiss Alps. Although the plot's machinations strain credulity at times, Ewan more than compensates with sly, self-conscious campiness, poking fun at the well-trodden tropes of the Euro crime thriller genre. Ewan also succeeds in drawing his characters' flaws and foibles with genuine insight and tenderness, including the novel's duplicitous villains. These adroitly developed dimensions allow for nice character depth and more than one surprising reversal.

Above all, though, Long Time Lost offers skillful and dazzling prose. Ewan revels in the atmospherics of his attractive settings. Descriptions of a standoff in a remote Swiss chalet, near the end of the novel, achieve a tense, foreboding grandeur: "She could still hear the distant boom of thunder far away across the Alps and glimpse the muted stutter of lightning." --Scott Neuffer, freelance journalist and fiction author.

Single mom Louise rarely has time to date, but one afternoon she meets the man of her dreams in a bar, shares passionate kisses with him, and then finds out the following Monday that he's her new boss.

Adele has just moved to North London and doesn't know anyone. One day she literally bumps into Louise on the street, after which the two women chat and become friends. The problem? Adele is the wife of David, Louise's new boss, although Adele seems unaware of the indiscretion between her husband and her new friend. Complicating matters further, Adele asks Louise not to tell David about their friendship, claiming he "can be a bit funny about mixing work life and home life."

As she gets to know David more and the women's friendship intensifies, Louise notices that the marriage is very odd, with David keeping a tight leash on his wife, calling her several times a day--always at the same times--to check up on her. Is Adele in an abusive, oppressive relationship? Should Louise try to rescue her? How does she do that when even she can't stay away from David?

This psychological thriller jumps back and forth in time and alternates between Louise's and Adele's first-person accounts, one of which is more unreliable than the other. Though the women sometimes make unwise choices, Pinborough keeps readers in the dark until the unpredictable ending that has generated its own hashtag (#WTFthatending) on social media. How readers feel about that ending will depend on how much they're willing to embrace events that go beyond reality. --Elyse Dinh-McCrillis, blogger at Pop Culture Nerd

Waves Passing in the Night: Walter Murch in the Land of the Astrophysicists by Lawrence Weschler, author of Pulitzer Prize finalist Mr. Wilson's Cabinet of Wonder, is a profile of legendary sound editor Walter Murch's persistent attempts to promote his potentially revelatory theories in the field of astrophysics. It might seem like an odd preoccupation for a man known for his groundbreaking work on films such as Apocalypse Now and The Godfather, but Weschler makes the case for Murch as a borderline-obsessive polymath with insatiable curiosity and far-reaching insights. Murch has spent decades investigating and promoting his own updated interpretation of the centuries-old Titius-Bode law, which hypothesized that--to simplify things greatly--planets and moons are distributed in predictable, mathematically consistent patterns. His ideas have a number of complicated corollaries, including an elegant link between the positions of the planets and notes on a musical scale.

Murch has run into difficulty introducing these ideas to the insular and highly technical community of astrophysicists, however, who consider his elaborations on Titius-Bode to be little more than numerology. One of the more obliging scientists Weschler talks to concludes, "Murch comes off as a charming amateur, who is having a good time playing with numbers, but there is nothing new or profound in what he is finding." Regardless of whether Murch's ideas are scientifically accurate, though, Waves Passing in the Night makes incisive points about the impenetrability of modern physics and the sad decline of the amateur scientist, whose unorthodox thinking once led to profound discoveries. --Hank Stephenson, bookseller, Flyleaf Books

In 2015, two West Baltimore computer geek teens engineered the city's largest-ever prescription drug heist and proceeded to upend and disrupt forever the traditional street-corner drug business. With police preoccupied by protests after Freddie Gray's death, Willie "Wax" Harris and James "Brick" Feeney hooked up with leaders of the Black Guerrilla Family street gang to steal pharmaceutical opiates worth $100 million from a dozen neighborhood drugstores. Possessing a premium product at zero cost and with their own algorithm, they set up a darknet-encrypted phone service for serious addicts and rookies to order pills anonymously at rock-bottom prices with Uber-like doorstep delivery. They called their business Pill City, and crime journalist Kevin Deutsch (The Triangle) tapped into his street resources and gang access to discover who they were and how they did it.

With direct connection to Wax and Brick over their encrypted lines and firsthand observation of the old-school street gangs fighting to protect their livelihood, Deutsch connects the dots. Pill City examines how these wonky sons of junkie moms bypassed probable college scholarships to take the express train to riches. Along the way, they unleashed bloody turf wars and seeded a multitude of largely poor African American addicts and overdose fatalities. Streetwise, brutal, deeply researched and filled with candid interviews from both sides of the law, Pill City is true-crime reporting with an edge--while the opiate epidemic it describes is still gaining steam across the United States. Pill city has become pill country. --Bruce Jacobs, founding partner, Watermark Books & Cafe, Wichita, Kan.

Parents are always nagging their kids to clean up their rooms. One messy little boy's mom is no different. She tells him, "If you don't clean up after yourself, we're going to have pests!" But really, what's the harm if his abandoned food scraps attract a few ants or a "little bitty mouse?" "What was the worst that could happen?"

As it happens, there is something worse than tiny pests, hence the book's title Great, Now We've Got Barbarians! When the crumbs and sticky messes around the house reach critical mass, the big, hulking barbarians infiltrate. Our grubby hero thinks Vlad, the first barbarian, is cute, and gives him a cupcake. But after Törr shows up, "seeking glory" (and cheese curls), the boy shoos him out of the house with a fly swatter. Things devolve quickly, with shaggy barbarians watching TV, stealing blankets to make forts and using school supplies to scratch their hairy backs. Even traps and the pest exterminator don't get rid of the "snoring, snarling, belching, badgering, grumbling, growling, loitering, looting, and lazing savages." It's time to take drastic measures: get out the rubber gloves and brooms and start cleaning.

Jason Carter Eaton (The Facttracker) and Mark Fearing (Tommy Can't Stop!) team up in a hilarious picture book that parents will love every bit as much as kids. The cartoonish barbarians, with their scruffy beards, horned helmets, scars and tattoos are like overgrown puppies, and just as threatening. Even dyed-in-the-wool slobs won't mind being on the receiving end of this fun cautionary tale. --Emilie Coulter, freelance writer and editor

Arriving with her mother from Port-au-Prince, Haiti, at Kennedy Airport, "holding hands for courage," 17-year-old Fabiola Toussaint, a U.S. citizen by birth, is ushered through Customs while immigration officials detain Manman. Fabiola is forced to leave her behind in New York, and lands alone in Detroit to face the only other family she has, uncertain of the "good, brand-new life" her mother promised. "Back in Haiti, it was always just me and Manman. But now, my world has ballooned and in it are these three cousins, and my aunt, too." Fabiola dares to hope: "Family takes care of each other." While she waits for her mother's release, her three cousins help her adapt to American English, high school in a large city and the social hierarchies on and off the street. Known as the "Three Bees"--Chantal is the brains, Donna the beauty, Pri the brawn--they hover as Fabiola navigates new relationships, including the sweet promise of first romance. Fabiola must figure out if--and how--she fits in as the fourth Bee.

Author Ibi Zoboi, who immigrated to Brooklyn, N.Y., from Haiti at four, "pulled from [her] own memories of living in between cultures" to write her electrifying debut novel; even as Fabiola morphs into an urban American teen, Zoboi keeps Fabiola intimately connected to Haitian traditions through Vodou, lwas (mystical spirits) and patron saints. Zoboi's raw, gritty, cautiously hopeful narrative captures a family in transition, working to support each other, stay together and do more than just survive the dangers and temptations on American Street. --Terry Hong, Smithsonian BookDragon

Photographer Joel Sartore set out to document every animal in captivity, asking the question "once we love something, won't we do anything to save it?" His hope for his National Geographic's Photo Ark project is that people will "look these animals in the eye, and then fall in love with creatures as dazzling as a pheasant or as odd as an octopus."

In Animal Ark, Sartore teams up with Newbery Medal-winning author Kwame Alexander (The Crossover; Out of Wonder) to add a poetic narrative to his stunning collection of big, bold animal photographs. On every page, an elephant, a bat, a snake or neon-bright grasshoppers are set against a black or white backdrop, with Alexander's playful yet pointed verse meandering around the images. Each creature is allotted the same amount of space, giving the chameleon ("turquoise and gold/ camouflage in the trees/ moods changing with the breeze") and the wolf ("HOWL like you mean it... the world is listening") equal air time. Several pages fold open to reveal still more exquisite photos, along with lyrical exhortations to respect and protect vipers, beetles, foxes and tigers. Because, Alexander writes, "The majestic and powerful are counting on us to help them."

A final foldout includes thumbnail photos of every animal showcased in the book, labeled with name, threatened status and where the creature can be found in the wild. Any reader who loves poring over detailed close-ups of animals--every feather, fang and shell ridge is visible--will happily lose themselves in Animal Ark. --Emilie Coulter, freelance writer and editor
