Wild Horse Island #4: Castaway Colt
Darby is nervous about starting at her new school in Hawaii, and when she gets there it's even worse than she thought. Within the first week she's made an enemy—her stuck-up cousin from the other side of the island.
At least Darby has a new horse to go home to: a beautiful colt that she found abandoned on a remote beach. Darby loves the colt, and she knows he needs a good home. But when her new worst enemy's parents call to rescue him, will Darby be able to let him go?
