IN THE DEPTHS, SOMETHING WAITS...

Acclaimed film director Jake Bentneus pilots a custom submersible to the bottom of Challenger Deep in the Pacific, the deepest point of any ocean of Earth. But something lurks at the hot hydrothermal vents, a creature -- a dinosaur -- too big to exist.

Gigadon.

It not only exists, but it follows him, hungrily, back to the surface. Later, a barely living Bentneus offers a $1 billion prize to anyone who can find and kill the monster. His best bet is renowned ichthyopaleontologist Sean Muir, who had predicted adapted dinosaurs lived at the bottom of the ocean.

But Muir is in solitary confinement at a maximum security prison for the death of his wife on a dive meant to confirm his theories. That doesn't matter -- Jake Bentneus has the means to get Muir out. He also has the means to put him back in prison forever if he doesn't kill Gigadon.

With a mind badly warped by a year in solitary confinement, can Muir solve the mystery of his wife's death while also traveling to the bottom of Challenger Deep to hunt and kill this impossible dinosaur?

If he wants to remain a free man, he'll have to do both.

He'll have to learn everything there is to know about
