I can’t say a lot more about the book, given how short it is. Not that I’m concerned I’d “spoil” it, exactly; because that implies giving away some information that explains the whole story. This isn’t a story that can be explained; rather, it’s one of those fictional works that makes you ask questions, that teases your brain a little. And I liked that a lot. One of the great things about science-fiction is how it can make you ponder deep questions like these.
IHU is a good, quick read for anyone who enjoys stories that make you think about complex, abstract concepts.
