"Twelve-year-old Olivia normally spends all year looking forward to her family's summer vacation in Florida. But not this year. Not when her parents have recently separated, and her father has to stay behind in Colorado. Olivia doesn't know what she'll do all summer without him. They've always been a pair, and she's never felt the same bond with her mother or younger sister. So Olivia plans to spend the summer laying low, and trying to ignore the hurt gnawing at her heart.

She can't just watch the beautiful creatures suffer"--Dust jacket.
