Gr 9 Up—Blue-haired Karou is 17, and, in addition to her unusual tresses, has other intriguing aspects to her personality. She supports her life as an art student in Prague by running errands for her foster parent, a supernatural chimera named Brimstone. These errands, which take Karou through strange portals to strange places to meet with even stranger individuals, reap rewards not only of money, but also wishes. Taylor builds a thoroughly tangible fantasy world wherein a complex parallel universe competes with far-flung geographic locales for gorgeously evoked images. Karou herself is a well-rendered character with convincing motivations: artistic and secretive, she longs for emotional connection and a sense of completeness. Her good friend Zuzana goes some way toward mitigating Karou's solitude, but a sour breakup with beautiful bad boy Kaz has left her feeling somewhat bereft. Taylor leads readers from this deceptively familiar trope into a turbulent battle between supernatural species: angel-beings seek the destruction of demonlike chimera in revenge for the burning of the archive of the seraph magi. The more Karou discovers about the battle, however, the less simple good and evil appear; the angels are not divine, the chimera are not evil, and genocide is apparently acceptable to both sides in this otherworldly war. Initially, the weakest part of the story appears to be the love story between Karou and Akiva, an angel of "shocking beauty"; there is little to support their instant bond until their true connection is disclosed. The suspense builds inexorably, and the philosophical as well as physical battles will hold action-oriented readers. The unfolding of character, place, and plot is smoothly intricate, and the conclusion is a beckoning door to the next volume.—Janice M. Del Negro, GSLIS Dominican University, River Forest, IL
