River Marked by Patricia Briggs
I just love Mercy Thompson series.
I've waited for a long time for Adam and Mercy to have some quality time together. And it was absolutely amazing - Adam is such a sweetheart - and at the same time scary as hell. There have been very intense moments in this series but vampires, fae, and werewolves have never frightened me as this creature in the river did. I was so scared during Mercy's dream and when she discovered herself by the river at night, I was actually hyperventilating.
I also realized that I have a strange habit while reading Mercy Thompson series. I read the first half of the book very quickly and then I start stalling because I don't want the story to end.
