50 SHADES meets David Fincher's THE GAME. Soon to be a major motion picture!

Would you kill a total stranger to save someone you love?

Sugar & Spice is the latest app craze taking the world by storm, but for Abby and Brendan Hollander, downloading it leads to a dangerous game of life and death. When the app assigns them a series of increasingly taboo tasks, they soon find themselves caught up in a twisted web of seduction and violence in this sexually charged dark thriller from the New York Times bestselling author of The Fourth Monkey—master of suspense, J.D. Barker.
