Every time I pick up one of Patricia Briggs' books I'm reminded of why I like her so much. Mercy remains an interesting character to me while so many other urban fantasy heroines have grown stale or ridiculous. Mercy is as she has always been: strong, yet vulnerable. This book puts her to the test when the members of her werewolf pack (including her husband) are snatched and held by an unknown group. There is plenty of magic and action, and lots of side characters from previous books get interesting scenes. If you're a fan of this series I don't think you'll be disappointed.
