A virtuosic debut novel in the tradition of Robert A. Heinlein
With his wife dead and buried, and life nearly over at 75, John Perry takes the only logical course of action left: he joins the army. Now better known as the Colonial Defense Force (CDF), Perry's service-of-choice has extended its reach into interstellar space to pave the way for human colonization of other planets while fending off marauding aliens.
The CDF has a trick up its sleeve that makes enlistment especially enticing for seniors: the promise of restoring their youth. After bonding with a group of fellow recruits who dub their clique the Old Farts, Perry finds himself in a new body crafted from his original DNA and upgraded for battle, including a brain-implanted computer. But all too quickly the Old Farts are separated, and Perry must fight for his life on various alien-infested battlegrounds.
