STAR STRUCK   Jesse James Dawson was once an ordinary man until he discovered that demons were real, and fighting them meant putting his own soul on the line. His new case is a beauty: Gretchen Keene, a Hollywood starlet who's become an unwitting catalyst in an all-out demon war. It's not her soul Jesse needs to protect, but the two-hundred-and-seventy-six others she's carting around--all the souls sold to spend just one night with the blonde bombshell. That's a lot of baggage, although it might explain her meteoric rise to fame. And it's all up for grabs by the demon world.   All Jesse has to do is keep her safe until New Years. Sounds easy.  But darkness is casting a nasty shadow in the California sun--a new unseen enemy is closing in and leaving Jesse to wonder, how do you fight something you can't see coming?
