Giana Insigne has never begged for anything in her life. As an Alpha weresiren and a princess of the Silva-Insigne crime syndicate, she was born to command-not to be summoned. But when the Grand Witches arrive to collect on a debt her family can no longer ignore, Giana finds herself dragged into a world of ancient magic and open chaos she was never meant to touch. Shaw Hawke is the most powerful witch alive. He was also, until recently, the most controlled. Now his magic is a wildfire with no walls - consuming everything around him, including himself. He has searched for an answer in every grimoire, every dark corner of the arcane world. And he believes he's found it. Her. Giana doesn't want to be anyone's salvation. But Shaw isn't asking, and the Grand Witches have already made sure she has no choice. Bound by a sudden empathy she doesn't understand and a pull she refuses to name, Giana must decide how far she's willing to go to survive a man who could unravel the world. And whether she's saving him-or becoming something far more dangerous alongside him.
