This book was amazing. The characters were realistic and it had a great story line. Having certain skills like tracking someone by the scent of their blood, being able to travel anywhere through the shadows, or seeing the future make the story very interesting. Liv is asked to help her friend find the person who murdered her husband and took her child. She must go deep into dangerous territory, where she is not very welcome. She is partnered with her ex-lover Cam to track this person. She has avoided Cam for the past 6 years. She has a secret that made her leave him, and now she isn't sure if she can keep away or if she even wants to. This story unfolds wonderfully and has you on the edge of your seat the whole time. I am looking forward to the next in the series, Shadow Bound, to read more about these characters and what happens next.
