The book is now available on Amazon, in paperback, hardcover, and now E-book.
You can also order an author-signed copy, by going to the publisher’s page. That option takes a little longer, of course, since the book comes to me for signature.
Note: On the publisher page, the default is set for paperback. Use the selector box near the bottom to switch to hardcover, and you’ll see the price change. The image below shows what the publisher’s order page looks like.
