Éstas son las sinopsis de las novelas:
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.
They are the special wing of the Colonial Defence Forces, elite troops created from DNA of the dead and turned into the perfect soldiers for the CDF’s toughest operations. The universe is a dangerous place for humanity, as three hostile races combine to halt our further expansion into space. Their linchpin is a turncoat scientist, Charles Boutin, who unfortunately knows the CDF’s biggest military secrets. And to prevail against this alliance, they must find out why Boutin did what he did. Jared Dirac is the only human able to provide answers, being a superhuman hybrid created form Boutin’s own DNA. Jared’s brain should therefore be able to access Boutin’s electronic memories . . . but when that appears to fail, Jared is instead passed on to the Ghost Brigades. Then, just as time is running out, Boutin’s memories slowly begin to surface within him . . . but all this while the enemy is planning something much worse for mankind than just military defeat.
