In the middle of the night, an explosion rocks Cambridge, Massachusetts and wakes Saul Signalman from bed. Blue, ethereal light pulses into the sky. A FaceTime call pulls him away from the view. It’s his wife, consumed in light, bidding him farewell. And then - the call ends. The explosion of light intensifies. The power goes out. Electronic devices stop working. In the dead of night, he races to his wife’s lab at the explosion’s core, but the building is missing. His wife is gone.

It was a legend in Fear County. A hideous, flesh-eating creature - part snake, part earthbound demon - that feasted on the blood of innocent children in the cold black heart of the Tennessee backwoods. But 10-year-old Jeb Sweeny knows the horrible stories are true. His best friend Mandy just disappeared. He also knows that no one has ever had the courage to go after the monster and put an end to its raging, bestial hunger. Until now.

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.

Bela and Lizzy, the dominant megalodon siblings from Angel's brood, have escaped the Tanaka Institute to roam the Salish Sea in British Columbia. While Jonas Taylor and his friend Mac attempt to either recapture or kill the "sisters," Jonas' son, David, embarks on his own adventure, motivated by revenge. Having witnessed his girlfriend's gruesome death, David has joined a Dubai prince's ocean expedition, tracking the 120-foot, hundred-ton Liopleurodon that escaped from the Panthalassa Sea.

On a top-secret dive into the Pacific Ocean's deepest canyon, Jonas Taylor found himself face-to-face with the largest and most ferocious predator in the history of the animal kingdom. The sole survivor of the mission, Taylor is haunted by what he's sure he saw but still can't prove exists-Carcharodon megalodon, the massive mother of the great white shark. The average prehistoric Meg weighs in at twenty tons and could tear apart a Tyrannosaurus rex in seconds.
