A Bullet Ballet - Tales of the Gatekeepers, #1

Jericho Porter was done. Out. Retired. Porter had managed the impossible: retiring from the Gatekeepers.alive. Now, he was ready to slow down and live life on his terms. He was finally free. He was also mistaken. When Malkah Hafeez, an ex-lover and fellow Gatekeeper, calls in a favor, he knows he should refuse. She saved his life once, right before betraying him, gifting him with two neutralizing bullets center mass and leaving him for dead.
He knows the smart play is to cut his losses, walk away, and disappear. He's done it before; he can do it again. If he does, he dies. Against every sense of self-preservation, he agrees to one more contract, joining Malkah's elite team as she completes the erasure of a high value target. Outgunned and outmanned, Porter must risk it all, unleashing the fearsome power of the Gatekeepers once again. In order to survive, he will have to step into his old world for one last dance with death.
