Ella Keyes thought the death of her twin brother Stuart was the last time she'd let life surprise her. She's up for tenure at her university, she escaped a doomed engagement, and her fluffy cat knows exactly when to expect her home every day. But when her grandmother passes and leaves Ella her house, Ella discovers that the third floor corridor of keys is more than just a family pun. The seemingly-unremarkable keys don't unlock any doors in the house, but each time Ella touches one, something in her life shifts. Her life's carefully-grown roots are ripped out of their soil. Flowers bloom...

After months of training a budding army of human/demon hybrids, Ayala and Carrick have worked out most of their differences. Who gets to use the bathroom first in the morning. Who’ll feed the bunny before they go out to make mayhem. Who gets to keep the jeeling claw they found in Forest Hills. You know, the important stuff.

But when Gregor sends them out with their battalion of shades and the mission quickly lands on the wrong side of Ayala’s “don’t kill norms” moral line, she quickly discovers that maybe morality wasn’t the motivator behind...

Stripped of her Silver Scale, made a pariah by the Summit, and with a price tag the size of Kentucky on her head, Ayala is on her own.

Gregor Gaskin is still missing, and when Ayala discovers he’s far outside the Mediator territory line, she will unravel more about the Summit than she ever thought possible.

Finding Gregor will take her far from home, but catching him might hit her right where she lives—and Gregor’s plans may just release hell on earth before she can stop him.
