One Earth. One species left alive. One hope for humanity’s survival. The Cycle of Extinctions is nearly complete. Sterile deserts smother every continent. Acidic waters foul every ocean. Starving humans teeter at the top of the food chain. In fact, they’re the last remaining link. But a doomed boy and girl may offer a seed of hope. Daoren and Heqet stand an even chance of celebrating their 20th birthdays. Like every 19-year-old prospect in Daqin Guojin, they must soon sit the Survival Aptitude Test. Only the smartest pass. The rest are harvested for grooll, the city-state’s sole food source and barter currency. If Daoren’s intellect can outpace his anxiety, he might earn the first perfect score in history and be named ruler. Heqet knows Daoren can’t do it without her, even if he’d be the last person to ask for help. Together, they hold the answers for saving humanity from extinction, but may never get the chance to share them with anyone. A murky cabal has been manipulating S. A.T. scores for the dull-witted children of the ruling caste. In so doing, they’ve violated a sacred law, triggered a widespread famine, and amassed a fortune in grooll. They’ll do anything to protect their wealth . . . even if it means ensuring Daoren and Heqet’s S. A.T. ends with the pair’s harvesting and humanity’s downfall. Survival Aptitude Test: Sound is the first book in Mike Sheriff’s post-apocalyptic sci-fi series, The Extinction Odyssey. Fans of classic dystopian tales like Soylent Green and Logan’s Run will enjoy this modern twist on humanity’s last gasp. | Survival Aptitude Test by Mike Sheriff, Paperback | Indigo Chapters
