Caitlin’s best friend is her pony, Jade, so when she goes away to summer camp for the first time, Jade goes too. At Beacon Lodge there are wonderful rides across the beach and into the sea, pony club games, and lessons—and there are new friends to be made: the other campers who have brought horses of their own. Then there’s the camp owners’ son, Zak. Caitlin has to deal with her first real crush and when Zak walks out after a furious argument with his parents, she tries to right what she feels was an injustice. After a series of mysterious events, Caitlyn’s sleuthing lands her and her pony in serious danger. Ultimately, Jade, whose swimming talent makes her a real sea horse, must prove her love and loyalty to Caitlin in an amazing demonstration of strength and bravery.
