Faefever by Karen Marie Moning

There isn't a lot I can say about this book without putting spoilers, but this is how I felt about it:

Holy. Crap. Once upon a time, when I read Darkfever, I knew this series would be darker, and much more intense than anything else I had read, but I had absolutely no clue how pitch dark things might get. Bloodfever was a shock, but it was NOTHING compared to this book. I have read that this book leads to Mac's darkest hour, and does it ever. The last few chapters of the book are chilling. Shocking. A warning: this book (and series) are NOT for the faint of heart. KMM isn't pulling any punches with this story. I will be anxiously awaiting Dreamfever, and I hope that what they say about it always being darkest before the dawn will come to be in the next installment. It breaks my heart to leave Mac there.
