The book is pretty inexpensive at $6 for the electronic version, although I would offer the caveat that because it’s scanned (presumably to keep the fantastic astronomical pictures and star charts in the book in a useful format), you’ll have better luck viewing it on a tablet or computer rather than a phone. I downloaded it and was looking at it on my Galaxy Tab, and it was readable and looked good. If I tried to look at it on my phone, I suspect I would get a headache from all the small text very quickly. And of course there would be the irony of taking a bright electronic tablet out with you to look at a dark night sky; you’d kill your night vision every time you looked down at the book.
Nevertheless, for those of you who don’t have the book and want it, or didn’t know that I wrote anything other than fiction and might be interested in seeing what else I write, this is a good intro. I’m actually very proud of this book; I had always wanted to write an astronomy book when I was younger so being able to do one was a genuine life goal. And as an added bonus, this book itself was very well received as beginner’s guide on everything that’s going on in the universe (and how to see it in the night sky). Check it out if you like.
