I bought this book to prepare for my AFF course this summer. It gives you a very thorough introduction to the sport, from a novices viewpoint. Starting with a breif summary of the basic terminology, continuing with a 50 page section describing your first jump in detail. This book contains sections dealing with everything a novice jumper or student-to-be could want to read up on. Including your progression through the different student levels, a breif history of skydiving, options availible for further progression within the sport, freefall body positions, how to handle more or less any emergency, spotting and of course an extensive section on skydiving equipment. It also contains an extensive glossary and index. The first time you read throgh it, you will probably feel a little overwhelmed by all the information, but it is a great resource to go back to and review as you progress with your training. It is probably the most detailed and accurate text on skydiving available to anybody thinking about taking up skydiving. I highly recommend it!
