I tried to buy your book from http://www.apress.com/book/view/9781430226321 and that page does NOT have a link to buy the eBook. It only has a link to buy the PRINT BOOK. I would assume that the eBook would be available before the print book ? What gives ?
Our book is still in the final stages of production and is not yet available for purchase on the apress site. However, it will be available very soon, and we appreciate your patience and interest in the book!
