A banker with a devil-may-care attitude and a smile that conceals a devilish impulse, a literary agent who is quick to anger and much too easy to manipulate, a mechanic with a desperate need to be liked by everyone, no matter the cost, and a psychologist who keeps all their secrets as well as his own...they meet every week in the dingy back room of Mackey's Steak and Ale Tavern in New York City. These men have one thing in common: They all suffer the sting of a broken heart.
Soon, anger turns to hate, rejection turns to rage, and the Broken Hearts Club spins violently out of control, exploding into murderous acts of vengeance. Detective Voort is assigned the case, determined to catch an exclusive killer who is always one death ahead...who appears to switch identities with each new victim...and who knows how to cover his tracks with cold efficiency. Breaking up may be hard to do...with the Broken Hearts Club, it's fatal.
