Carcharodon megalodon, prehistoric ancestors of the shark, survive in the abyss, trapped in place by seven miles of frigid ocean water. Paleontologist Jonas Taylor, helping a friend recover scientific sensing units that have been mysteriously damaged in the ocean trench, watches helplessly as the "Meg" that destroys his friend's capsule is then ripped to shreds by its mate?who then migrates to the surface. The female Meg is pregnant and hungry and far too large to be contained. This first novel offers nonstop excitement, as Taylor and other scientists try to corral the beast, while idiotic tourists and news crews flock to the scene to watch. Only Taylor understands the size, power, and ferocity of the Meg.
