Water, water everywhere... and lots of books to read. It seems that water, both literally and metaphorically, has taken the book world by storm of late:

Charles Finch's The Woman in the Water also builds a mystery out of a woman's body found in the Thames (as the title suggests). The novel is a prequel to Finch's popular Victorian-era detective series, offering long-time readers and those new to the series a look at Charles Lenox's first case.

For nonfiction fans looking for more literal accounts of the water around us, there is Tristan Gooley's How to Read Water: Clues and Pattern from Puddles to the Sea--with advice on using water to understand the natural world better. Or Steven Solomon's book Water: The Epic Struggle for Wealth, Power and Civilization, which outlines how world conflicts have been driven by a need for access to fresh water.
