Losing the Moonstone Wolf Pack

Addie and Theo. Werewolf mates. Hopelessly in love. Sounds cheesy, right? Well, for them, cheesy is a relief. Their relationship hasn't exactly been easy, but things are picking up, and everything is perfect, now that Theo has promised to never leave Addie.
But nothing good lasts forever.
Two newcomers have arrived, both of the "supernatural" kind. These people are slowly driving a wedge between Addie and Theo, and when Addie disappears, everyone is distraught. Though everyone knew how distressed Theo would be, no one expected the whole of the Moonstone Wolf Pack to crumble to pieces.
