The Diviners by Libba Bray

The Diviners is a standout book among those authored by Libba Bray.  Set in during the roaring twenties, Evie O'Neill has been shipped off to New York City from rural Ohio because her gossip got her in trouble with the locals.  Evie can't wait to cut loose in NYC, thinking she will experience speakeasies, the Ziegfeld girls and all NYC has to offer.  The only catch is that she must live with her uncle Will and his unhealthy obsession with the occult.  Evie worries that her uncle will discover her darkest sercret:  a supernatural power that up till now has only brought her trouble.  But when the police find a murdered girl branded with a cryptic symbol and Will is called to the scene, Evie realizes her gift could help catch a serial killer. 
Libba Bray has written a fantastic historical book where the glittering surface of the Roaring Twenties hides a mystical horror creeping across the country.  This book is not to be missed.
