Chain of Thorns is a Shadowhunters novel.
Cordelia Carstairs has lost everything that matters to her. In only a few short weeks, she has seen her father murdered, her plans to become parabatai with her best friend, Lucie, destroyed, and her marriage to James Herondale crumble before her eyes. Even worse, she is now bound to an ancient demon, Lilith, stripping her of her power as a Shadowhunter.
