More a novel of ideas than a "yarn," The Book of Joan's characters exist primarily as symbols, vehicles for ideology. This quality brought to mind older modes of storytelling, such as ancient Greek and Roman epics, fairy tales, and didactic poems. Everything is heightened--the language, the stakes, the characters. At first I highlighted many passages, dazzled by the prose, but the lyric language reached a critical mass about a third of the way through, and I became distracted by linguistic tics such as the overuse of "wrong" as an adjective. It could also be hard to read some of the graphically violent passages.
Nevertheless, I applaud this novel's ingenuity, its reworking of Joan of Arc's story and interesting notions regarding gender and sex.
