At first, it’s a struggle to know what’s going on … certainly complicated by a brilliant physicist and paranoid killer main character. No spoiler: this is in the first few pages. However, keep at it, go with the flow, and it comes together. When that happens, the beauty of Harrison’s universe becomes apparent in its weird multi-dimensional glory. This initial confusion is part of the experience, expected from good hard sci-fi. This world is not easily explained. It’s not very pleasant. Yet in the end, this is a good novel with some amazingly written passages.
