The description of the book is a very important part of its sales. It needs to be written carefully and with precision.When writing the description for an ebook, you should write in a smooth and natural style. You can try your own style as well as follow examples from other writers. Write about what the book is about, not only what it does or how it works. Avoid using technical jargon as much as possible - that will make your book look less appealing to potential readers.
