Luna Morgan has seven days before her wolf spirit dies—but her Alpha mate Declan and her family don't know she's terminal, and they're forcing her to test a dangerous experimental ritual meant for her fragile twin sister Sage. When Morgan finally agrees, she signs the mate rejection papers and plans to die on the table rather than reveal the truth that could destroy them all. But the Northern Pack's ruthless Alpha Kieran discovers her secret and offers her something she never expected: sanctuary, vengeance, and a choice that could save her sister's life at the cost of her own. As Declan closes in with Council representatives and pack law on his side, Morgan must decide how far she'll go to protect the people who never protected her—and whether dying human is better than living as the mate who was never enough. In a world where wolf spirits are everything, losing yours doesn't just mean death—it means becoming invisible to everyone you ever loved.
