Werewolves waiting for their mate...
Cousins, Kadar and Ethan are the Guardians of the Portals… the stones that lead to other dimensions. They have been waiting for what seemed like forever for their Complement to arrive. When that happens, their Triad will be complete.

A Mermaid looking for love...
Marina is on a touring holiday around Scotland. The instant she steps into the Stone Circle at Callanish, she knows something momentous is about to happen. She didn’t expect a simple touch on a glowing barbell symbol would transport her to another dimension… Or to wake to find the two men of her dreams beside her, telling her she was their mate!
