Collin has heard countless tales of adventure from his dad and grandpa. As his tenth birthday approaches, he’s determined to find one for himself.

One day, he hears a mysterious heartbeat over the sea. Farther down the beach, he also finds an abandoned submarine. Curious, he steps inside, and realizes it’s anything but abandoned. When the crew asks him to join their mission, Collin knows this is the adventure he’s been searching for. But as the mission unfolds, Collin discovers it’s actually two in one: finding the source of the heartbeat, and what happens afterward.

Join Collin as he embraces the adventure of a lifetime—and discovers the magic that will linger long after it’s over.
