Ember spends her Friday nights lurking in the bad parts of town, killing fairies. It’s either that, or become a victim to 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 a team of 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.
