Trick. Treat. Take out the trash.

Welcome to the most unhinged Mulvaney party yet. The costumes are couture, the littles are under lock and key, and the ultimate villain is about to get exactly what she deserves.

What starts as a Halloween gala turns into a house-wide hunt as the Mulvaneys, Jericho's Boys, and the men of Elite close ranks to end a monster's reign for good. One brother takes a hit but refuses to stay down. Asa proves why psychopaths deliver the sweetest revenge. Mac and Archer demonstrate exactly what they teach at the Watch. Jericho, Atticus, Lucas, and August bond over a little creative torture. And in the heart of Aiden's workshop, a righteous invention guarantees permanent justice.

Between traps, taunts, and vigilante vows, this anthology serves dark humor, feral family, and heat-plus bonus stories from the night before the party and an exclusive masked hook-up that lights the fuse for a future Jericho's Boys couple. Cameos abound, couples get spooky and spicy, and the Mulvaney littles prove the apple doesn't fall far from the tree.

Perfect for readers who crave found family with teeth, Villains & Vigilantes delivers a cathartic, high-octane coda to a long-running evil-and a reminder that when the Mulvaneys say they'll keep you safe, they mean it.
