Black Dawn — L.J. Smith

VAMPIRE PRINCE

First he put her in a dungeon. Then he realized they were soulmates. Now he wants to make her a vampire princess.

Maggie Neely is a short, spunky sixteen-year-old with auburn hair and an iron will. When her brother turns up missing, she's determined to find him. But she never suspects that the trail will lead her into the most secret heart of the Night World, a kingdom where no outsider has stepped in five hundred years.

The kingdom is ruled by the young vampire prince Delos... who keeps all humans as slaves. When Delos falls in love with Maggie, he frees her and demands that she join him in his life of dark pleasure. He's handsome, he's romantic -- Maggie can hardly resist him. But did he kill Maggie's brother? And who are the strange people searching the kingdom for a Wild Power? Maggie won't give up until she learns the truth -- even if it means destroying Delos and his secret land. If he doesn't destroy her first....
