Emile Delaurier is a beautiful militant revolutionary, a living beacon of righteous justice for the world. For Renaire, an artist in a constant battle against the demons in the bottle, it was obsession at first sight. His devotion led to two years of homicidal partnership as Renaire followed Delaurier in his ruthless quest for equality through the death of the corrupt, like a murderous Robin Hood.

Then Delaurier breaks his pattern, leading Renaire into Russia to kill a reporter with no immoral background, and gives no explanation for his actions.

When Interpol contacts Renaire, he already has enough problems—keeping Delaurier alive, dealing with the shift in their relationship, and surviving the broken past that still haunts him. But when he learns what Interpol wants from him, Renaire must face the truth about Delaurier: that a noble man isn’t always a good one. He’s left with a choice no man should ever have to make—to follow his heart or his morals.
