The Diviners is set to release in September but Paramount  has stepped in and preemptively optioned the novel.  The Diviners is the first is a four part series published by Little Brown.

From Variety:

Paramount has made a preemptive purchase of The Diviners, a young-adult novel by Libba Bray. Fake Empire’s Josh Schwartz and Stephanie Savage will be the producers. The book will be published in September by Little Brown, the first of a four-part series. It was a sizable purchase for the studio. Book is set in the 1920s and follows a group of young New Yorkers with mysterious powers who play a dramatic role in a battle of good vs. evil when a series of occult-based murders begin to terrify the city. The author will adapt the script and be exec producer. The hope is to launch a franchise.

Last week at BEA the Diviners was one of the hottest arcs going and I am happy to say I scored a copy.  Guess this is moving straight to the top of my TBR pile.
