Necessary Evils #3.5-5
Necessary Evils Vol. 2: Books 3.5-5
Books 3.5-5: Damaged • Headcase • Mad Man
The Mulvaneys are back—more unhinged, more obsessive, and more dangerously in love than ever. This boxset continues the bestselling Necessary Evils series with three scorching, violent, twisted romances featuring childhood trauma, enemies-to-lovers chaos, twin psychopaths, fashionista vigilantes, and enough dark humor to balance all the bodies.
In Damaged, Dimitri Castallanos has loved Arlo Miller since they were children, back when obsession meant petty crime and protection meant survival. As adults, both pretend the past is behind them, until one violent act forces them back into each other’s lives. With a body to hide, twenty-four hours to build an alibi, and feelings they can’t outrun, they must finally decide which is falling in love or getting away with murder.
Headcase follows Asa Mulvaney, one half of a psychopathic whole, suddenly separated from his twin for the first time in his life. Enter Zane Scott, an ambitious crime blogger determined to expose the Mulvaneys and the irresistible disaster who derails his plans. When a rash of campus “suicides” reveals a deadly conspiracy, Asa drags Zane into a world of killers, obsession, and one very possessive twin who always gets what he wants.
In Mad Man, Avi Mulvaney meets his match in Felix Navarro, a sharp-tongued fashionista vigilante who loathes Avi almost as much as he wants him. Forced together on a dangerous mission with only one bed between them, hate turns to heat, heat turns to obsession, and Avi has one week to prove Felix belongs with him…and with the Mulvaney family of beautifully broken monsters.
If you love queer villains, chaotic soulmates, dark humor, and disturbingly heartfelt psychopath romance, this boxset delivers three complete HEAs and zero cliffhangers.

I’ve read the individual books multiple times. I absolutely LOVE August (he’s my favorite), so it’s a no brainer that I’ll read the box set. Why not? Because I didn’t keep up with the dates I started, all three volumes will have the same dates AND review. 🤷🏽♀️

I will always be a fan of the murder twins & core four shenanigans, in any form.
