Shadowless Assassin

"Leon Spade, orphaned and experimented on as a child, awakens the power to accelerate his own time after the death of his adoptive father, Blake. As the legendary independent assassin “Shadowless,” he single-handedly destroys the Black Snake Gang and rescues Ada Hearts, a gifted forger known as “Mirror.” The two marry and try to live quietly running a dessert shop. Their peace is shattered when old enemies, rival powers, and the true mastermind—Ronald Diamond, architect of decades of human experiments—come after them. Ronald seeks to claim Leon’s evolved body as the final vessel for his consciousness network. With allies old and new, Leon and Ada confront the conspiracy, reverse the mind-altering painting Elysium, and end the cycle of control once and for all."
