Everything is about to change for Sophie Beaumont. Sophie has moved her entire life; never staying in one place too long. She didn’t understand why… until now. Sophie is a shifter. A wolf shifter and she has a lot to learn. About being herself, being a wolf, and being what she needs to be to protect her pack. On top of that, her intense feelings for the pack’s Alpha, Caeden, threatens to ruin everything. Especially if the rival pack, the Grimms, find out that Sophie is not the human she claims to be.

Nothing will be the same for Sophie Beaumont. Now that she’s an Alpha she has to learn to be a leader. But unlike with Caeden, it doesn’t come naturally for her. Sophie doesn’t want to tell her friends how high to jump. She just wants to be normal. Caeden and Sophie travel to Germany to meet with Sophie’s parents in the hopes of learning more about being mates and “why them?” But Sophie’s parents prove not to know much. Everything is just speculation. Then, the news of Peter Grimm’s murder sends the Williams’ pack into a tailspin. With Travis as Alpha what is he capable of?

First she was an Outsider. Then she became an Insider. And now… she’s going to have to be a Fighter. Nothing goes as planned for Sophie Beaumont. She thought that Travis had been defeated. She believed that they would all finally be safe. But Travis never left. He has a plan and it's one that no one could have ever guessed. It will take everything Caeden and Sophie’s pack has to take him down and make sure his heart never beats again. This will be the greatest fight that they have ever experienced. An all out war. Who will live? And who will die?

It’s all been leading to this for Caeden and Sophie Williams. This should be the happiest time of their life. They’re married and expecting a baby, but Travis is still out there, and they both know he won’t rest until he gets what he wants. The question is, what does he want? They’ll have to figure it out if they ever want to have their happily ever after. The end is near. Who will be left standing when it's over?
