In short: Dennis Pagen has written THE book on paragliding for beginners to intermediate pilots. This book covers it all. Clearly illustrated, easy to read. I use this book as a 'refresher' each season before I begin flying. He covers all the nuts and bolts of the various topics that make up paragliding, from how to hook your risers to your harness to how to ridge soar. I have read most of the books out there on paragliding, and this one covers more than all the others combined. If you are a serious paraglider pilot who wants a good manual for refreshing, or prospective pilot who wants to learn all you can before you begin lessons, this is THE book to buy.
