The other reviewers have said it already. This is an entertaining story with some imaginative ideas about the future. I bought it ages ago and have read it a few times.
On the strength of this book I then bought, eventually, all the other books in the series. Big mistake. I now hate it whenever the scotsman appears and skip entire sections to avoid the author's (or authors' I guess as there are two of them!) mangled interpretation of what a scots accent sounds like. And I am really truly sick of the obsession with having food 'recipes' scattered throughout the books. I want to read an adventure, not a cookery book.
So get this by all means, you'll enjoy it. Just be aware that the later books are not of the same quality, something that regularly happens with pulp fiction series like this, unfortunately.
