Firewalker

Picking up right where Trial By Fire left off, Firewalker is another sexy, fast-paced, heartbreaking thrill ride from internationally bestselling author Josephine Angelini!
I'm a Witch and Witches burn.
Lily is back in her own universe, and she's ready to relax with Rowan. True, she almost died in the Pyre that fueled their escape, and must hide her magic for the safety of the world, but compared to fighting the monstrous Woven and leading armies in the alternate Salem, life is looking good.
You think I'm a monster, but my choices, as ruthless as they seem, are justified.
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'll have to find a way to make her come back.
