The story is told in language as clear and beautiful as an illuminated manuscript, with characters who spring instantly to life. The fairy-tale conventions give it a sense of timelessness and omnipresence without once becoming twee or unwieldy. Blackall's luminous black-and-white illustrations and medieval-style spot art add to this feeling and are wonderful at conveying emotion through posture, pose, and delicate linework. . . . A book with an angelic soul: large, sharp, and uncompromising.
