There was something decidedly unusual about the dead body found floating off the coast of Cuba. The wool of his garment, while only twenty years old, was from an animal extinct for over nine thousand years. A group of professional scuba divers, including Lord Henry Basingstoke and his friend, Rodrigo Quintas, eagerly search the ocean bed for clues. But when they find a mysterious underwater vehicle, a fun vacation becomes an obsessive quest to be the first to solve the mystery. A daring journey back through time takes them to a hidden land of rainforests, deadly creatures, and a doomed civilization. A place where nothing is what it seems. And the longer they stay, the more their adventure becomes, quite literally, a race against time.
