I found this to be a rather interesting collaboration by two authors I never would have expected to get together. I've admittedly not read very much by Terry Pratchett, probably because his style of fictional humor simply isn't my favorite genre. I am however a big fan of Stephen Baxter, so I thought that might make this worth a go. I was not disappointed.

I found the blended writing style to be well executed, with Terry Pratchett adding just a slight touch of humor without loosing the seriousness of the multiverse concept being explored in the story. The book is a good length and shouldn't take too long to read, though it is clearly the beginning of a multi-book series; the ending left it wide open.

In general it was a very enjoyable read and I look forward to the next installment. At some point they really need to make some merchandise to go with this series, like a stepper kit (supply your own potato). :)
