Some call them ghost sharks, the oldest and strangest looking creatures in the sea. Marine biologist Brad Whitley has studied chimaera fish all his life. He thought he knew everything about them. He was wrong. Warming ocean temperatures free legions of prehistoric chimaera fish from their methane ice suspended animation. Now, in a corner of the Bermuda Triangle, the ocean waters run red. The 400 million year old massive killing machines know no mercy, destroying everything in their path. It will take Whitley, his climatologist ex-wife and the entire US Navy to stop them in the bloodiest battle ever seen on the high seas.
