Packt has published my latest book, Magento Beginner's Guide. They offer a sample chapter on their website, "Categories and Attributes." They also took a section out of a chapter and published it as an article on their website, "Creating Tax Rules in Magento."
The sample chapter, article, and chapter descriptions on their website should give you an accurate and thorough impression of the book's style and content. If you're a Magento user, check it out. And if you've bought the book, as always, I like to hear from my readers. Send me compliments and complaints by clicking on the email link in my profile.
