Bloody Crystal - Department 57, #10

Cerys is happy working in the bar in her hometown of Llandudno, Wales. Nobody knows her secret until she meets dark, brooding Rhodri Tryfanwy. He knows her at once, because he's like her. Vampire. Rhodri sees the ethereal Cerys as everything he's ever wanted. Light to his darkness, he takes her and she responds. Long nights of passion give him the hope he'd almost given up on finding. But events move too fast, and Rhodri has to return to the dangerous, violent world of Department 57.
His old adversary, Geoffrey Wilkinson, gives him no choice. Thrown into a new world, Cerys is forced to leave everything she knows behind to search for him. She is Rhodri's only chance. Without her help, he'll be taken apart, piece by piece, and sold to people who will exploit what he is to make money and take power they're not entitled to. Without her love, he is dead. Without his love, she will want to die.
Only together can they hope to survive.
