Everyone at Hawthorne Lake Country Club saw Willa Ames-Rowan climb into a boat with James Gregory, the club's heir apparent. And everyone at Hawthorne Lake Country Club watched him return—alone. No one believes that Willa's drowning was an accident. After all, she held the club record for the fifteen-hundred-meter freestyle. And the Gregory family has a history of making troublesome girls disappear. They all know James Gregory killed her. But none of them will say a word.

Enter the W.A.R.: four girls, four very different motives to avenge Willa's death, and only one rule: destroy the Gregory family at any cost. Innocence is lost, battles are won, and the pursuit of the truth ultimately threatens to destroy them all.
