Never promise a fey anything.
With magic leaking back into our world, working the nightshift as a paramedic comes with danger. But I handle it. I’ve got a shotgun for the zombies and my lycanthropic rage hasn’t escaped my apartment. Life is normal-ish. All that changes when I’m called to help a dying fey knight and I make a promise.
There’s a little girl with big eyes and a heart-rending sniffle. I can’t say no. Of course she’s not human. She’s their key to opening the long-closed gates and feasting on humanity.
Now an entire world I know nothing about is trying to kill me. And if I don’t protect her, the teeth around my heart will finish the job. If I learn fast and bargain the right parts of my soul, the girl and I might make it out alive. Otherwise the cruelest winter will freeze everyone solid.
