They took his family. Now he's coming for everything.

Once a lethal mercenary, Patrick McMillan thought he had left the bloodshed behind. With his wife and daughter are brutally murdered, his past comes roaring back—and this time, he's not following anyone's rules.

Driven by vengeance and haunted by guilt, Patrick sets out to destroy the man responsible. His hunt leads him into the underground chaos of a city ruled by crime syndicates and buried secrets. Unexpectedly, he crosses paths with Marina, a woman who reminds him too much of his past—and her own reasons for joining the fight.

What begins as a fragile alliance turns into something deeper, something neither of them can afford to want. But in a world where loyalty gets you killed and justice is a lie sold to the highest bidder, Patrick must decide how far he's willing to go—and who he's willing to lose—before his vengeance consumes what little he has left.

By My Hand is a gritty, emotionally charged thriller about love forged in violence, the weight of loss, and the cost of revenge.
