Look for Me by MoonlighteBook - 2008?
When sixteen-year-old Cynda goes to stay with her father and his second wife, Susan, at their remote bed-and-breakfast inn in Maine, everything starts off well despite legends about ghosts and a murder at the inn. But Cynda feels like a visitor in Dad's new life, an outsider. Then intense, handsome stranger Vincent Morthanos arrives at the inn and seems to return Cynda's interest. At first she is blind to the subtle, insistent signs that Vincent is not what he seems-that he is, in fact, a vampire. Can Cynda free herself-and her family-from Vincent's power before it's too late? Full-bodied characterizations and page-turning suspense ensure that this eerie, riveting novel will appeal to middle school fans of mystery and horror.
