With the haunting mystery of The Roanoke Girls, the atmospheric landscape of Where the Crawdads Sing and the darkness of Gillian Flynn's Sharp Objects, All the Wicked Girls is a gripping thriller with a huge heart from an exceptional talent.

Everyone loves Summer Ryan. A model student and musical prodigy, she's a ray of light in the struggling small town of Grace, Alabama - especially compared to her troubled sister, Raine. Then Summer vanishes.

Raine throws herself into the investigation, aided by a most unlikely ally, but the closer she gets to the truth, the more dangerous her search becomes.

And perhaps there was always more to Summer than met the eye . . .
