Avery Bloom, who's bookish, intense, and afraid of many things, particularly deep water, lives in New York City. Bett Devlin, who's fearless, outgoing, and loves all animals as well as the ocean, lives in California. What they have in common is that they are both twelve years old, and are both being raised by single, gay dads. When their dads fall in love, Bett and Avery are sent, against their will, to the same sleepaway camp. Their dads hope that they will find common ground and become friends, and possibly even sisters. But things soon go off the rails for the girls, and they find themselves on a summer adventure that neither of them could have predicted.

Unhappy about being sent to the same summer camp after their fathers start dating, Bett and Avery, two girls, age eleven, eventually begin scheming to get the couple back together after a break-up. Told entirely through letters, emails and text messages.
