The story continues....The first time around, the kids had to figure out a way to work together and survive on a deserted island. This was hard for a blended family that had just been put together—Vanessa and Buzz’s dad married Jane and Carter’s mom—but they still managed to make it and get in touch with their parents... Or so they thought. Stranded on a new island, with dangers they've never before encountered, Carter, Vanessa, Buzz, and Jane find themselves in a desperate situation. They've raced for their lives, but their adventure isn't over yet. Before they can finally escape Shadow Island, they'll have to pull together all their strength and courage and tackle one final challenge.
