Cullen Bright is the greatest athlete in human history. With over fifty victories in the Enhanced Pentathlon, no one can fight, shoot, or run like him—but it's not enough. Adrift and bored with wealth and fame, he finds his cause when an alien enemy launches a savage war of extermination against The Ten human star systems under Unity control. In a flash of anger, he enlists in the Unity Marines, determined to bring his limitless talent to a cause that is spiraling into chaos and madness. But Cullen will learn that being a Marine isn't a solo sport, and respect isn't given—it's earned. Taught by hard lessons and harder people, he enters the battlefield where losing is not an option, and there are no medals. Join Cullen and his squad as he pushes back against an enemy that doesn't just want victory—they want humanity erased. But Cullen never gave up on the field, or the ring, or during an upbringing of pain and sorrow, and he's not about to start now. Still, he's only one man, and there are questions out there in the endless black of space that he must answer— Can a former athlete lead Marines into battle. . . and can one man be a catalyst for victory in the greatest war humanity has ever known?
