Ryder Hayes is the league's most explosive hockey star, infamous as the "Mad Dog" for his violent temper and unpredictable breakdowns. Years of injuries, public pressure, and manipulation by his agent have left him unable to trust anyone, including himself. When head coach Damian becomes the only man who can pull him back from the edge, Ryder willingly enters a private relationship built on control, obedience, and a black leather collar. But what begins behind locked doors soon collides with the professional world. A league investigation, an intrusive ex, a controlling agent, old rivals, leaked footage, and Ryder's damaged shoulder threaten both his career and the secret he shares with Damian. Forced to compete without Damian beside him, Ryder must prove that obedience is not the same as dependence. By the championship game, he has learned to stand on his own, and in front of the entire league, he finally chooses for himself who he wants beside him.
