Very impressive "under the hood" book for Drupal. Not only does it discuss the "good things" to do, but also the "bad things" to avoid. The writing was very clear, although at times the examples seemed a little forced.

This must-have book for any aspiring Drupal developer or old pro is a great way to learn Drupal programming as well as reference for review of concepts that one doesn't use day in and day out. It is not a how to build a site book rather it is a programming book.
