The Stronger Chase by Cap Daniels

They made him a target . . . He made them pay the price.
After learning that he’d been the target of the most elaborate infiltration scheme by Russian intelligence since the Cold War, American covert operative and assassin, Chase Fulton, vows to coax the mastermind of the complex scheme out of the Kremlin and into the open, where he’ll exact his revenge. An unexpected encounter with a mysterious figure who claims to have known Chase’s father opens doors into a world Chase isn’t prepared to enter. From the high seas of the North Atlantic to the Shenandoah Valley outside Washington D.C., Chase must face the demons of his emotions, as well as the forces of evil determined to destroy him, as he resolves to become more focused, deadlier, and stronger than ever.
