Payback is paradise in this start to a trilogy from New York Times bestselling author of To All the Boys I've Loved Before (soon to be a major motion picture!), Jenny Han, and New York Times bestselling author of The List , Siobhan Vivian. Postcard-perfect Jar Island is home to charming tourist shops, pristine beaches, amazing oceanfront homes--and three girls secretly plotting revenge. KAT is sick and tired of being bullied by her former best friend. LILLIA has always looked out for her little sister, so when she discovers that one of her guy friends has been secretly hooking up with her, she's going to put a stop to it. MARY is perpetually haunted by a traumatic event from years past, and the boy who's responsible has yet to get what's coming to him. None of the girls can act on their revenge fantasies alone without being suspected. But together...anything is possible. With an alliance in place, there will be no more "I wish I'd said..." or "If I could go back and do things differently..." These girls will show Jar Island that revenge is a dish best enjoyed together.
