Blackstone Academy trains heirs, killers, and monsters. Aoife O’Brien is supposed to marry for power and die quietly after. She wasn’t meant to fall in love. She wasn’t meant to fight back. And she definitely wasn’t meant to survive long enough to choose. Matteo Messina is the future of a mafia dynasty. Ruthless. Controlled. Untouchable. He knows better than to want an O’Brien. He knows better than to protect the enemy. But when Aoife stands on the edge, broken, hunted, and ready to disappear. Matteo makes a choice that changes everything. Now there are knives in the dark. Poison in the blood. And a war coming that will tear Blackstone apart. Because loving her means betraying his world. And letting her go means watching her die.
