Three brides were given to him. Only one can be kept.

Diarmuid O'Sullivan has what he wanted. The family is his, the enterprise runs clean from Dublin outward, and the O'Sullivan name means what it meant before the order came. He is at the height of his power.

He is also out of time.

Two brides remain. Niamh, loyal in a way that has started to frighten him. Selene, clever and reckless and far too close to the truth about a woman nobody will name. One of them will be his consort. The other will be sent away — and Diarmuid has spent three years learning exactly what happens to a bride he discards.

Amira taught him that.

Victor has sent a warning in the shape of a man as dangerous as Diarmuid himself. The order wants what it's owed. The game has reached its final move.

He plans to smash the board.

Some Kings are monsters. This one has one thing left to lose.

When Kings Fall is the third and final book of the O'Sullivan's Brides trilogy — a dark Irish mafia romance told through four points of view. Begin with When Kings Rise.
