What would you do if you were given a second chance? Titus Briggs is an Earth Defense soldier, a grunt, a decorated war hero—it's all he's ever known. So when a career-ending injury leaves him lying in a hospital bed, missing both legs, he struggles to accept his new reality. He can no longer walk, which means he can no longer fight. That is, until a mysterious colonel arrives and offers Titus the opportunity to step into a new kind of war, a new kind of fight. To become a new kind of soldier. Mobile Combat Suits—MOCOMS—represent the next stage in human warfare. They enable soldiers to fight like never before. Stronger. Faster. Bristling with weaponry. Far more lethal. And even a broken veteran like Titus can operate one… if he can find the heart, grit, and determination needed to pass selection. Now, with the end of humanity upon him, Titus must become the Able-Bodied Soldier.
