They were best friends—until love tore them apart.

Jacob is ready to rule Blackthorn, but sobriety isn’t his only battle. His family demands he take a wife and produce an heir, yet his heart has never forgotten the best friend he hurt—Miles. The boy he once pushed away. The man who now looks at him with nothing but cold indifference.

Miles buried his heartbreak years ago. First, Jacob shattered him. Then Indie vanished after a summer of stolen nights, hidden secrets, and falling hopelessly in love. It was never meant to last—she’s always running. But now she’s back, desperate for his help to destroy the demons she’s been fleeing from for years. Too bad he’s too angry to care.

Now, the two people who broke him most are together. But when they make a shocking proposition—that they only want each other if they can have him too—Miles is forced to face the truth he’s spent years denying.

Desire still burns, tangled with pain, betrayal, and secrets that could destroy them all. As old wounds resurface and new threats close in, will they risk it all for an unconventional love that was always meant to be?

AUTHOR NOTE

Mutual Obsession is a dark, sinful MMF mafia romance packed with forbidden passion, second chances, and an obsession too strong to resist. It is book two in the Rivals of Blackthorn series, and while it’s an interconnected standalone with a HEA that can be read on its own, if you do want to read the series, it’s recommended you start with book one, Prized Possession. Includes MM, spicy scenes, and dark themes; check content warnings.

The Rivals of Blackthorn Series is set in Emma Luna’s Beautifully Brutal World, and whilst you don’t have to read the books in the Beautifully Brutal series before reading the Rivals of Blackthorn, there are characters that crossover, and it may contain minor spoilers. If you’d like to read in order, start with Black Wedding in The Beautifully Brutal Series first.
