Ten years ago, Penelope Isabella Aaron had been a pain in Brock Mann's you-know-what. Much has changed in a decade: "PIA", as he code-named her, has grown up and is about to attend her first Alliance of Planets summit conference, and Brock has been transformed into a cyborg after a near-fatal attack. Now a secret agent with Cyber Operations, a covert paramilitary organization, Brock gets called in, not when the going gets tough, but when the going gets impossible. So when he's unexpectedly assigned to escort Penelope to the summit meeting, he balks at babysitting a prissy ambassador. But after a terrorist bombing, a crash landing on a hostile planet, and a growing attraction to his protectee, Operation: PIA may become his most impossible assignment yet.
