Bestselling and critically acclaimed authors, Jenny Han, author of To All the Boys I’ve Loved Before and The Summer I Turned Pretty, and Siobhan Vivian, team up in this thrilling trilogy. Perfect for fans of Pretty Little Liars and Big Little Lies.

Idyllic Jar Island is home to charming tourist shops, pristine beaches, and stunning seaside homes, while three girls quietly plot their revenge.

Kat is tired of being deceived. One more harsh word from her former best friend or her secret boyfriend acting as if she doesn't exist will be the last straw. Those two deserve to feel as bad as they made her feel. But if she were to try something, everyone would immediately suspect her…

Lillia is ready to stop pretending that her final year will be so wonderful. After everything she went through this summer with her best friend Rennie and the way her friends look at her, she begins to understand that these "friendships" are nothing but abusive behavior.

Mary has just returned to Jar Island after a traumatic event that has haunted her for years. She is determined to put it behind her, but when she sees Reeve, she is sure that this will happen only when he feels the same pain that his actions caused.

This story shows that there are consequences for bad behavior and that revenge may require collaboration.
