Pro Drupal Development
Apress has a new book out called 
Pro Drupal Development. I’ve been reading through it and have found it to be very helpful. The book starts you right off with building a module. It covers what is in the various elements and node variables. It also has a chapter covering use of jQuery with Drupal. If you really want to extend your Drupal install and know php and javascript, this is your book. This is for hard core Drupal users and hackers. Here is a recent slashdot review of Pro Drupal Development.
When I started using Drupal I needed something simpler. I needed something else to learn how to navigate the Drupal interface. The Drupal online handbook is invaluable. There is also a good book Drupal: Creating Blogs, Forums, Portals, And Community Websites published by PackT Publishers that helps you use Drupal. If all you want to do is install Drupal and start adding content to your site, sort of out of the box, then this book will help you with that.
