Sometimes the fiercest battle a man faces is against himself. In the hidden alleyways of New York City, George "Tank" Tankersley defeated what he believed were demons. But the victory cost too much. Tank joined the Army in the hope of outrunning the guilt haunting himaonly to stumble into a vast and deadly conspiracy, the enemies he'd hoped to never encounter again, and the arms of the brilliant, eccentric scientist tasked with saving humanity. In a world where the line between dark magic and alien science is thin, Dr. Lev Underwood must reverse engineer recovered alien technology to give humans a fighting chance against the extraterrestrial beings who consider Earth nothing more than a petri dish. His old friend, Colonel Clyde Aldrich, wants to protect Lev from entanglement with the scarred and emotionally volatile young soldier, but Lev cannot help the pull he feels toward Tank. Still, his first loyalty is to the secret government program, and love might have to take a back seat to protecting the world. But if he can find a way, Lev wants both.
