My rating: 5 of 5 stars
Not sure how much Pratchett and how much Baxter there is in this book, I suspect mostly Baxter, given the circumstances. It is the last and final (probably) part of a series that plays on one version of the 'many worlds'. I found (again) the characters believable and human (well, at least one of the main characters is not exactly human). The plot has an enormous scope and you very likely do need to have read the previous books for it to make sense. It draws on what seemed to me a variant of the 'grey goo' self-replicator problem -but I'll stop at that. I enjoyed being in that world once again, I found it an easy and absorbing read.
