About the Book: Five years after the events of the previous phase in the series, sorcery and moral boundaries shift in unexpected ways. Veterans of the magical war return to new roles and new threats emerge—most notably the Anti‑Sanctuary, a group of sorcerers believing in mortal subjugation. The skeleton detective Skulduggery Pleasant enlists Valkyrie Cain’s help to investigate the disappearance of Temper Fray, which leads them into a city of sorcery (“Roarhaven”), secret plots and an escalating battle between sorcerers and mortals.
