Evelyn is devastated as she thinks her true mate is murdered and she has more or less given up on life. That is until she realizes what the secret organization, which captured her, is doing to both shapeshifters and humans.
After she's forced to participate in underground fights her compulsion to do the right thing forces her back into action. The biggest problem is that she's cut off from her family and pack, with no way to contact them. The only thing she has left is these weird dreams she's been having and all of them include her sweet Amy.
