Our view
A science-fantasy debut that mixes outer space, magic and a murder mystery, and sets a wisecracking, very modern heroine in a grim, tomb-like world. Some readers find that contrast a hurdle and are put off by the opening pages; those who push past them can be won over completely. Suited to readers who like their dark settings cut with irreverence, and who will give a book a second try.
