RaveNPROne of the pleasures of The Book of Joan is its take-no-prisoners disregard for genre boundaries. Its searing fusion of literary fiction and reimagined history and science-fiction thriller and eco-fantasy make it a kind of sister text to Jeff VanderMeer's ineffable Southern Reach trilogy. Yuknavitch is a bold and ecstatic writer, wallowing in sex and filth and decay and violence and nature and love with equal relish ... The effect is dizzying and, at times, disorienting, but there is always a vibrant forward motion to the text, and a ferocious, unmistakable perspective: Even in the wreckage of a post-human nightmare, humanity never really changes.
