NEW YORK TIMES BESTSELLER - A NEW YORKER BEST BOOK OF THE YEAR - NOW IN DEVELOPMENT AS AN HBO LIMITED SERIES

From the acclaimed author of Gone Girl, "a riveting tale of true horror by a writer who has all the gifts to pull it off" (Chicago Tribune)

"Sensuous and chilling . . . a propulsive and twisty mystery."--Entertainment Weekly

Libby Day was seven when her mother and two sisters were murdered in "The Satan Sacrifice of Kinnakee, Kansas." She survived--and famously testified that her fifteen-year-old brother, Ben, was the killer. Twenty-five years later, the Kill Club--a secret society obsessed with notorious crimes--locates Libby and pumps her for details. They hope to discover proof that may free Ben.

Libby hopes to turn a profit off her tragic history: She'll reconnect with the players from that night and report her findings to the club--for a fee. As Libby's search takes her from shabby Missouri strip clubs to abandoned Oklahoma tourist towns, the unimaginable truth emerges, and Libby finds herself right back where she started--on the run from a killer.
