Satisfied Sam

The depths of the ocean are as dark and unknowable as the emptiness of space. But to Doctor Clair Margraves, a marine biologist, there’s nothing quite like the thrill of discovery to sate her curiosity. Her next adventure will see her piloting a deep-submersion vehicle on its maiden voyage to the bottom of the Mariana Trench. But something strange is going on at the bottom of the ocean floor, something she’s never seen before. And she intends to find out what.

Pre-med student Coral is on vacation in Idaho when something terrible happens. The black cloud is followed by a wildfire and searing heat that lasts for days. She survives deep in a cave but emerges days later to find the world transformed, with blackened trees, an ash-filled sky, and no living creatures stirring - except for her. So begins her desperate journey to find water and food and other survivors...and the answer to the mystery of what happened.
