Sam Cooper had just moved to Harper’s Inlet when he met Tony. Tony’s
father owned a marina. Sam, Tony, and Tyler took scuba lessons together.
Tony got them in for free. After they completed the course, the boys
decided to try out their new skills in the real world … the ocean. The
only problem was, no one had permission. While Tony’s father was
away on a buying trip, the boys took one of the rental sailboats out
for their diving adventure. Everything went well until the biggest storm
Tony had ever seen blew up from out of nowhere, and the boys found
themselves stranded on Lost Island. But, if they thought the worst
had happened, they were wrong. The boys discovered a secret hideout that
was used by men in high powered speedboats. Sam and his friends knew
the men were up to something, only they didn’t know what. They had
to find a way to stop them, but how? And, even if they did, the boys
could never tell anyone about it. Join Sam Cooper, Tony, and Tyler on
their scary scuba, ocean, island adventure.
