In 24 short days*, my (along with the awesome George W. Clingerman) first book will be released:
Professional Windows Phone 7 Game Development: Creating Games using XNA Game Studio 4 
(or as we like to call it, that damned 550 page monstrosity that nearly killed us)
Weighing in at 552 pages and featuring a foreward by the legendary James Silva (Ska Studios, creator of The Dishwasher: Dead Samurai, The Dishwasher: Vampire Smile, I MAED A GAME W1TH Z0MB1ES 1NIT!!!1, and more...) this book gives thorough coverage of XNA 4.0 as it relates to Windows Phone 7.
The book is written in a light, conversational tone, which means (unlike some books) you won't be compelled to gouge your eyes out with a rusty spork after reading the first few pages. At least, that’s the intent. If you do feel compelled to engage in some feats of eye-gouging sporkage, we (the authors of this book) would like to point out that we are not responsible and that seeking the help of a mental health professional might be advised. (We’re not qualified to dispense medical advice either.)
The book is structured to introduce relevant material first, with code snippets and samples of how to use various phone features and XNA concepts, with helpful side notes along the way. After you've been exposed to a few chapters worth of concepts, you get the chance to bring them together by building a game that leverages those features.
This book contains THREE (3!) complete games, including: Drive & Dodge (a racing game), Poker Dice (roll dice to make poker hand combinations) and Picture Puzzle (take a photo and turn it into a jigsaw puzzle.)
Writing this book has been an incredible experience, and we hope reading it will be equally informative for all of you. We’re also happy to announce there will be a Kindle edition available, along with various other electronic media.
Get your copy from Wiley.com, Amazon.com, Barnes & Noble, and anywhere else awesome books are sold.
*more or less… some sites list the publication date as early march, but the official street date is 2/21/2011
