They say you can never truly leave the underworld, but Peter thought he had finally traded his blood-stained past for the quiet shelves of a used bookstore. After decades of serving as the legendary muscle for the Glory Club, he was ready to fade into obscurity. He was wrong. Ambushed and left for dead by the very people he built, Peter prepared for the end, only to wake up in the one thing he never expected: his own teenage body. Now, with the peak physical prowess of his youth and a lifetime of lethal experience, the master assassin is coming out of retirement. It is time for a reckoning. Peter is trading in his books for cold, hard vengeance, and the Glory Club is about to learn that you do not cross a legend, no matter what age he is. Get ready for a high-octane, hilarious, and brutal ride as one man tears down an entire criminal empire from the inside out.
