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.
