Grade 5–9—In this sequel to Skulduggery Pleasant (HarperCollins, 2007), 13-year-old Valkyrie Cain and her mentor, the living skeleton detective, are faced with the return of the evil Baron Vengeous, who has been freed from prison. Vengeous is trying to reanimate the Grotesquery, a monster made up of pieces of a variety of evil creatures. If his scheme is successful, the Faceless Ones, "the terrible dark gods, exiled from this world," will return. Faced with treachery within the ranks of good magicians, Valkyrie and Skulduggery must rely on their own Elemental magical powers and a few trusted allies to confront Vengeous's magic and helpers, such as the vampire Dusk and Billy-Ray Sanguine, who has the ability to tunnel underground. One magical action sequence follows another as Valkyrie must find the courage to face what seem to be insurmountable foes. Humorous conversations between Valkyrie and Skulduggery add flavor to this generally dark and often-violent novel, as does the girl's appreciation of the dichotomy between her evil-fighting life and that of a quiet student lived by her reflection while she's off saving the world. Fans of the first book will particularly enjoy the new schemes and evil creatures found here. While the back-and-forth between Skulduggery and Vengeous's forces repeats a few too many times, readers looking for a mix of magic and action will find it here
