In Kelley Armstrong's Frostbitten the female werewolf Elena Michaels returns and together with her mate Clay; the enforcer of the American pack investigates some brutal deaths near Anchorage, Alaska. 
 Elena Michaels is without a doubt Kelley's favorite character as this is the fourth book about her, of ten in the series, and it's not hard to understand as her introductions to the supernatural world is somewhat unusual. At the beginning of this book it's clear that Elena has accepted what happened and is starting to plan for her future together with Clay and their young twins. 
 This book has an interesting and compelling mix of actions worthy of the best detective novel and character development where Elena slowly transforms from an insecure working mother to a kick-ass alpha candidate.
