Elite Guardians bodyguard/former sniper CHRISTINA SHERMAN has protected uncooperative clients before-but this time, well her client is bossy, headstrong and occasionally eats off the floor. Yes, he's a highly trained military working dog, but certainly her skills could be put to better use, right? Not according to former Special Forces Air Commando GREY PARKER. He needs her help to protect his dog while he undergoes an experimental surgery that could restore his ability to walk. He just needs someone to keep his canine partner safe. Most of all, Grey wants back on his feet so he can track down a deranged scientist known as The Scavenger who unleashed a nerve agent that left Grey sidelined in a wheelchair. When an attempt is made on Grey's life, and dead bodies begin piling up-with evidence the same toxin is responsible-suddenly Christina is tasked with keeping both dog and soldier alive...and with them, the secrets that could stop a terrorist attack. But this time, even Christina might be in over her head. Dive into the exciting ignition to the Elite Guardians Collection.
