I'm A What?!

Olive's life was fairly normal as an Assistance dog (Service dog) user working in a small pet store in London. Little does he know he's surrounded by a whole separate world. A world full of magic and a secret second community full of creatures and their mates. What happens to Olive's life when they meet two handsome strangers who happen to be knee deep in both worlds! What's going to happen when he gets told something about his life he's never thought could happen in his life?
