Lily is back in her own universe, and she's ready to start a new life with Rowan by her side. True, she almost died in the Pyre that fueled their escape from New Salem, and must hide her magic for the safety of everyone she cares about, but compared to fighting the Woven, the monstrous creatures inhabiting the alternate Salem, life is looking pretty good. Unfortunately, Lillian, ruthless ruler of the 13 Cities, is not willing to let Lily go that easily. If she can’t persuade Lily to return to her world, she will force her to come back by doing away with the ones she loves.
