There was something decidedly unusual about the dead man found floating off the coast of Cuba. For one thing, the wool of his garment, while only twenty years old, had been shorn 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 the secret of time travel in the deep, a fun vacation becomes an obsessive quest to solve the mystery before anyone else finds out. This involves a daring journey back through time, to a hidden land of rainforests, deadly creatures, and a mysterious 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.
