Jumia Books THE TREASURE HUNTERS 1(JAMES PATTERSON.)

Professor Kidd and his wife have raised their four children on the boat from which they travel around the world seeking treasure. But after their mom goes missing in Cyprus and their father disappears -- and possibly drowns -- during a storm, the kids decide to stay on the boat and continue their work. Along the way, they face constant peril from both the authorities and a band of scuba ninjas led by their father's nemesis, a fellow treasure hunter named Nathan Collier. But as they work together using their unique talents (Tommy is good at sailing, Storm is a genius and good with computers, and brother-sister twins Bick and Beck are tough and hardworking), they continue to discover real treasure. They also discover some big family secrets -- and even a way to get their mother back.
