This is an ambitious, genre bending book. It combines elements of magical realism with post apocalyptic science fiction. Probably the most important social contribution is implicit; it imagines a world after climate change, and makes that seem very real and very immediate. It is also full of interesting ideas about utopia and the nature of religion, and includes some thoughtful critiques of some of those ideas. For me the ending was too neat, and if I'm honest, a bit too mystical. That's a matter of taste of course, but I felt like it lost the important tension between the emotional and the intellectual that was the backbone of the rest of the book,
