The exciting sequel to “Three Chambered Heart” Book 1. Casey Solstein is a brilliant young palaeontologist with the Boston Museum of Natural History. Her speciality is large carnivores. She is also a collector of old science fiction magazines. While at a market she happens upon a series of magazines that outline a supposedly fictional story about an impossibly big, and black, crocodile in the jungles of New Guinea. What interests Casey is that the description of the creature almost perfectly matches that of a recent prehistoric fossil find in the Amazon Basin. This creature was 50 to 80 feet long - three times bigger than a T-Rex. Only trouble is, the magazine was published before the discovery was made. Casey’s investigation leads her inexorably to the Ramu Valley, and the terrifying force that lurks there.
