On her thirteenth birthday, Agatha is given a terrifying assignment--her first ghost. Soon after, her Aunt Hattie disappears. Clues begin to crawl out of the shadows, each one pulling Agatha deeper into danger-through the midnight halls of a local funeral home and into a haunted Mardi Gras mask shop after dark. Something ancient and vengeful is lurking in Biloxi. Can Agatha master her untested powers in time to save her aunt, or will she be the next victim of an old ghost with a grudge?
