This was the best Mercy Thompson book so far! Mercy's former boss, mentor and friend is arrested for a murder he did not commit, and Mercy decides that she needs to do whatever she can, as usual to help him get free. And, as usual, she gets herself into trouble. Adam is there to pull her out of a couple of scrapes, and I loved his intensity throughout this book. Although it felt a tiny bit slow in the beginning, the last 1/4 of this book was so fantastic! I felt the emotion that Mercy, Adam and even Ben were feeling, so intensely. I loved this story and will likely go right on to the next installment immediately.
