Carson and Tate have been running for months, trying to evade the JIA so they don't end up lab specimens for the ruthless organization. In a last ditch effort, Carson and Tate head to Alaska, where other Changelings are congregating in an attempt to find a way to control their thoughts and emotions when they shift to their animal forms.

With their future on the line, Carson realizes the most important part of his life will forever be his mate, Tate, but how can he trust a man who never tells him the whole truth?
