Biomedical warfare. Nuclear disaster. Cross-species genetics... After World War III triggers a series of global seismic catastrophes, the Earths orbit around the sun is shifted, initiating a domino effect of atmospheric and environmental changes. The result is a non-stop hostile environment where it seems almost every remaining life form, plant and animal alike, has evolved to kill. Humans inevitably are forced to flee into advanced underground bunkers to escape the threats that lie above, and their only hope of survival as a race lies uncertainly within the youngest, who have the most potential in adapting to survive the new, almost uninhabitable world. Its been twenty years since the Descent. While self-sufficient in the best version of the sense, the Groom Lake Nuclear Bunker is begining to fail, and its inhabitants are facing critical life-and-death decisions that will write the very future, or end, of the once dominant race that now clings for survival at the bottom of the food chain. But when a team of scouts from the bunker lead by 19-year-old Maverick Evolon make a mysterious discovery in the ruins of a old town nearby, their lives shift yet again, and they are tasked with a dangerous mission risking stakes higher than any of them couldve ever imagined. The fate of mankind rests on the shoulders of Maverick and his team, and a dark web of secrecy and lies stands alongside the war-torn surface world and the genetic mutations that inhabit it in the odds stacked against them. Will mankind persevere in the face of extinction? Or will humans succumb to natures grand retalliation? A breathtaking epic of humanity's last hope and its struggle to reclaim its place in a world riddled with radiation, plague, and nightmarish biological mutations, Gavin L Zane's "Shift: Horizons" will have you looking at the world in a whole new way...
