I'm disappointed that the Kindle version hasn't been updated for the Kindle Fire. In the appendix, for instance, when you click on items that start with A you get items that start with E. The same is true for the Glossary. And if you are trying to locate a certain numbered paragraph there are no hyperlinks to get you there. It's still very awkward to use as an E-book and could be much improved. As far as the actual book, however, this is an excellant catechism of the Catholic Church, in fact, the best available. And paying $10. for it is a steal...if only it were more user friendly!
