I stayed up way too late finishing this book. I could NOT put it down.
Which is why I am definitely taking a break of a book or two. I will absolutely gulp every one of these down back-to-back if I don't assert some control over myself.
Anyway, Mercy finds herself up against the fae. She was up against vampires last time and werewolf politics in the first one. I love the world PB has created. It's so dangerous but, as this book proves, no one is helpless.
I highly recommend this series to fans of Urban Fantasy. There's romantic through line, but it's not romance. There are a lot of great characters, and all of them care deeply for Mercy. Again, as I've said already, she's completely worthy of all the love.
