Jemma Hartman knows that her first summer at beautiful Camp Star Lake is going to be amazing. There will be swimming, sailing, and overnight trips – not to mention her best friend, Tammy, who moved away a year ago. But when Tammy's cousin, Brooke, decides to come to camp as well, Jemma's perfect summer starts to crumble. Brooke never laughs at Jemma's jokes, and she thinks she rules the cabin. She even convinces Tammy to be her sailing partner, sticking Jemma with the camp weirdo. Jemma just can't understand why Tammy wants to spend all her time with Brooke. And is it really possible to make new friends but keep the old, like the song says, or does Jemma simply need to let go?

Recalling the camp she attended as a child, Brenda A. Ferber offers an endearing look at friendships lost and found.
