Blood Bound - Patricia Briggs There was a lot less romance in this book than I'd expected, but I didn't even realize that until after I'd finished reading the book, because while I was reading, I was so enthralled with the plot and Mercy, that I didn't even notice when Adam and Sam hadn't appeared for chapters on end. That's just how awesome Mercy's characters is. All the other aspects of this book are also pretty nice, but the characters are definitely 95% of the reason why I love this series so much.
