In her past life, Ivy was the strongest White Wolf, fighting her entire life for the Blackthorn pack — only to be left for dead on the battlefield by her own father, Victor. Reborn, she marries Ronan, the strongest Alpha of the North, hides her White Wolf identity, and asks for nothing more than to be a protected, "useless" Luna. Ronan dotes on her. Her in-laws treat her like their own daughter. Her sister-in-law Bryn shields her. Only Finn, her brother-in-law, looks down on her. Then Victor colludes with Kane, Alpha of the Ironfang pack, and slips into the northern estate hidden aboard a Blackthorn herb cart. Grant and Finn are gravely wounded; Mara nearly dies shielding Ivy. Forced to reveal her White Wolf nature, Ivy defeats Kane and guards the Wolf King's Seal. When Ronan returns, he asks no questions and demands no favors — he only asks if she's hurt. Victor and Ivy's sister Sera arrive, intending to take Ivy away and put Sera in her place as Ronan's Luna. Ronan and Ivy both refuse. In the end, Victor is deposed and exiled; Sera returns to Blackthorn, her favor lost. Ivy stays with the Blackwood family — she refuses to be anyone's weapon ever again, and begins to learn, for the first time, how to live as family.
