So good. SO. GOOD. UNNNFFFFFF. I can't even. This might be my favorite Mercy book yet. I am so stoked for Frost Burned.
The series had started to peter out for me a bit after the last one, but this brought it roaring back. Also, major points for being able to picture the scenery exactly because I've camped there many a time (luckily didn't encounter any river beasties).
The only thing I felt was lacking was a really good sex scene between Mercy and Adam. After the last several books with their near-perfect sexual tension, didn't we deserve that? Maybe. Maybe not. I might just have to go find some fanfiction.
