This book will teach you how to publish your book on the iPad. From idea through distribution and sales, you will learn every step of the writing and publishing process. When have finished this book you will be able to confidently write, publish and sell your own book on the Apple iPad's iBookstore—with just a few clicks.
On the one hand, you can't learn "every step of the writing and publishing process" from an 88 page book. On the other hand, you can find most of the content in this book on the web. But on the gripping hand, I think this might be a useful book for a complete newbie. I sometimes buy books like this when getting into something for the first time.
