Yes it's true, for the past few months we've been hard at work with a lot of other co-authors on The Definitive Guide to Drupal 7.
The Definitive Guide to Drupal 7 accelerates people along the Drupal learning curve by covering all aspects of building web sites with Drupal: architecture and configuration; module development; front end development; running projects sustainably; participating in the community; and contributing to Drupal's code and documentation.
