Pro Drupal Development is an excellent developer’s book for the content management system: Drupal. With twenty-three chapters, it highlights such topics as
how to create a module.” Our website design company relies on such good reference books and this one really shines.

If you are at all interested in technology and provide web design services, this is a must-have book for Drupal developers. One critisism I do have, however, is that it does not go into further detail in Views and Content Construction Kit, but only really references the handbook on Drupal’s website. I also like that the authors go into design best practices.
