She vowed she'd never return to Faerie...but vows were made to be broken.

As a human girl, Chloe is perfectly happy being back in the mortal realm where she belongs. She's even become the town apothecary. When a fae from her past shows up begging her to return to Faerie, she utterly refuses.

But then she finds out an angry group of mortals are using iron to hold an entire castle full of fae hostage. And of course, the hostages include Chloe's older sister and her sister's beloved.

Reluctantly, Chloe packs a bag for what is supposed to be a short trip to Faerie.

But the mortals are more powerful than she expected. To fuel them, they have weapons, flames, and revenge. They won't stop until they control every court in Faerie.

With the help of a new and mysterious magic and a too-handsome-for-his-own-good fae companion, Chloe has to save Faerie before her sister and the other fae are killed.
