Blood Prize by Ken Grace

It's 5am and Tom Fox is running, trying to save his life, but he can't escape the images that revisit his mind; vivid pictures of a woman with her throat torn open and the mutilation of a young man in a back alley of London.

Tom is on everyone's most wanted list, yet he's no felon. He flees, hunted like his father for what he knows. If Tom is to survive, he must locate an alien technology called the Prize, before it falls into the hands of the despots who are chasing him.
