Shadowghast
(Book)

"On the eve of Ghastly Night, a hypnotic stage magician, Caliastra, checks in to Eerie-on-Sea's Grand Nautilus Hotel. She's arrived with her entourage to put on a show – and she claims to be related to Herbert Lemon. Caliastra's act is so shadowy and strange that Herbie's friend Violet wonders if dark forces are at work, but Herbie won't hear a word said against his new relation. Meanwhile, folk are disappearing from the town, and no one knows why. There is an Eerie legend that goes back to the dawn of time, about a creature made of darkness that devours the shadows of the living. Could the Shadowghast have really returned?"--publisher's website.
