Pervasive Games has appeared in Amazon: At least amazon.com, amazon.co.uk, amazon.ca and amazon.de seem to list it already. The details you can see there are preliminary, and will get fixed when the book gets out. Most notably, Annika is not listed among the primary authors, which at least needs to be corrected.
Very rewarding to see it up there. After all, we started to write sometime in spring-summer 2007.
(We don’t have an exact publication date yet. Amazons predict different dates in June-July, but we hope to hit the shelves earlier).
