Carol is the best assassin, although she is a human she is given the hardest missions, the ones that seemed impossible, but she is able to accomplish them all. One day she is called to fulfill one mission no one has been able to complete. Kill the Alpha King and his Beta. No one has been able to get near them, and if they have they are immortal. No one can lay a hand on them, meaning they are a menace to society and have to be annihilated. Carol accepts the mission, thinking it will be complicated but she would be the only one to accomplish, however she may soon realize this is the only mission she won’t be able to accomplish. As soon as she meets the Beta she feels something, an attraction that couldn’t be explained, meaning one thing. The Beta, the man she has to kill was her mate, and now she has to make an impossible decision. Will she betray the people she cares for? Or is she going to accept this bond and all that comes with it?
