Blood of Phobos. Infinity Unleashed, #1

Time. It wears on us all. Like gravity, it weighs us down with the influence of age. And eventually, time runs out. For every one of us-everyone except Skot. The enormous human/alien hybrid gifted with immortality has to watch as everything he knows succumbs to the crawl of time. A hybrid of human and the much larger deHera species, Skot bears witness to the genocide of the native deHera people. Never truly accepted by the humans, he finds himself banished to a dystopian planet in the savage throes of its own death.
Fighting off vicious monsters and the suicidal pull of isolation, the warrior without a world stumbles upon a way out. After a ship crash-lands on the planet, Skot finds a group of survivors and defends them against the ferocious predators. A second vessel arrives, rescuing Skot and the remaining survivors and returning them to Earth IV. Their arrival on the home world of the humans sets off a chaotic chain of events which forces Skot to fight for his life on another unforgiving planet.
Upon learning of the Skot's defiance of age, Damon Tyberian, the self-obsessed world leader, devises a plot to tap into his agelessness and offer it to the wealthy elite-for a substantial profit. Tyberian enlists the planet's military resources as well as the Sentury Guard (a select force of government sanctioned assassins) to hunt down the hybrid. The huge warrior discovers a diverse group of allies in his effort to evade capture.
Lorelei Chryses, the lead scientist of the stranded expedition, Jensen Wagner, a smartass pilot, and a tough computer hacking teenage girl named Bug all unite around the fugitive. A castoff from two worlds, the deHera/human hybrid finds himself in the position to save both. But fighting off the military, assassins and mercenaries could prove too daunting a task-even for someone who can't seem to die.
