Ember has a little problem...Fairies want her dead.

Ember spends her Friday nights lurking in the bad parts of town, killing fairies. It’s either that, or become a victim of their flesh-eating hunger.

Then she meets Remy, a fae who, despite getting on her nerves, isn’t evil. He tells her that a shadow has been consuming his world, changing its inhabitants and letting destructive beasts into his city. He is searching for his brother who went missing during the catastrophe.

When mercenaries come for Ember, she has little choice but to join Remy in his quest. Together, they decide to bait a trap. What they find reveals the destruction of the fae world means the end of the human world, too–and it’s Ember’s fault.
