Front End Drupal: Designing, Theming, Scripting

From the author:

While other Drupal books focus on module development, Front End Drupal is 100% focused on issues of site design, behavior, usability, and management. The authors show how to style Drupal sites, make the most of Drupal’s powerful templating system, build sophisticated community sites, streamline site management, and build more portable, flexible themes. You’ll also gain hands-on experience through several case studies that walk you through site creation and customization from start to finish.
