In the aftermath of a deadly alien invasion, a band of survivors fights on... Join Marcus Steele and the toughest commando team fighting for humanity's survival—Hell Squad. Battle-hardened, alpha soldiers. Men and women who never give up. Heroes will rise...when they have someone to live for. Includes: Hell Squad: Marcus - In a world gone to hell, Elle Milton—once the darling of the Sydney social scene—has carved a role for herself as the communications officer for the toughest commando team fighting for humanity's survival—Hell Squad. It's her chance to make a difference and make up for horrible past mistakes...despite the fact that its battle-hardened commander never wanted her on his team. When Hell Squad is tasked with destroying a strategic alien facility, Elle knows they need her skills in the field. But first she must go head to head with Marcus Steele and convince him she won't be a liability. Hell Squad: Cruz - Battle-hardened soldier Cruz Ramos is running on empty. As second-in-command of the deadliest commando squad fighting the invading aliens, he doesn't know why he's fighting anymore. He's seen too much destruction, devastation, and far too much death. Still, every day he goes out to protect those humans left, and every day the growing numbness threatens to take over. Until a mysterious woman emerges from the ruins of destroyed Sydney and saves him from a pack of rampaging aliens. Hell Squad: Gabe - Hell Squad soldier Gabe Jackson has lost everything that mattered, including his twin brother. Now he just wants to kill the invading aliens anyway he knows how...and he knows a lot of ways. Previously part of a secret Army super-soldier project, he's faster, stronger, deadlier...but on the inside, he's a mass of rage, and pain, and grief—all waiting for a chance to drag him under. Until he finds her.
