Commander Jonas Taylor is tasked with piloting the US Navy's most advanced submersible, the DSV Sea Cliff, to the bottom of Challenger Deep — 36,000 feet below the surface — into what is very much an undiscovered country. What he finds there — a remnant population of luminous, prehistoric Megalodons — will change the course of the rest of his life. In this prequel to his New York Times Bestseller, Meg: A Novel of Deep Terror, Alten sets the stage for the popular suspense series to follow. Fans of Meg will find it a must for offering insight into key characters' backstories, but the novella-length work also stands alone as a bite-sized tale of deep-sea suspense.
