As Jim wrote, all the chapters of our LINQ book are now available through Manning's Early Access Program (MEAP). The book is now in final review and the paper version is due later this year or in January. This is great to get close to completion on this project!
Go an see the result by yourself (the first chapter is available for free in PDF).
I'm also happy to see that LINQ in Action gets its first public reviews. See what Ben Hall thinks about the book, for instance.
