drupal7-bible or the-definitive-guide-to-drupal-7 ? Searching the internet these two books seem to be suitable for me. I'm beginning to learn Drupal7 but am no novice with CMS software. I used TYPO3 for years. I'm not looking for a technical bible but the book has to go in-deep into all aspects of Drupal7 (no older versions). Any recommendations?
