Blue Twilight
By Maggie Shayne, 2005
Series: Wings in the Night

"The idyllic town of Endover, New Hampshire, looks innocent. But below its surface a thirst and a desire both powerful and ancient boil fiercely. When two girls go missing, only one person can delve deep enough to find them - Maxine Stuart, a private investigator who has finally started to believe. "Mad Maxie" understands why she was asked to help - no living mortal knows as much about the undead as she." (from Amazon.com)
