Right before they started high school, Colette's best friend, Sadie, dumped her. Three years later, Colette is still lonely. She tries to be perfect for everyone left in her life: her parents, her younger brothers, her church youth group, even her boyfriend, Mark. But Colette is restless. And she misses Sadie.

Then Sadie tells Colette that she needs her old friend to join her on a family vacation to the Greek Islands, one that leaves in only a few days, and Colette is shocked to hear their old magic word: need. And she finds herself agreeing.

Colette tries to relax and enjoy her Grecian surroundings but it's not easy to go on vacation with the person who hurt you most in the world. When the reason for the trip finally surfaces, Colette finds out this is not just a fun vacation. Sadie has kept an enormous secret from Colette for years . . . forever. It's a summer full of surprises, but that just might be what Colette needs.
