Item of interest: Ms. Mirai chides the publisher (us) for creating the Kindle ebook as a print replica, meaning that it follows the paperback page by page and the type size isn't adjustable (although you can zoom in to magnify parts of the page). We did that because the novel has multiple types of text distinguished by different typography (a lot of work went into that), and we thought it'd be confusing to the reader if we lost most of that graphic variation in a standard ebook. We tried the published version on our own tablets and it seemed to work fine, though we realized it probably wouldn't work well on a phone.
This is the only one of our ebooks that uses the print replica format. We'd be happy to hear readers' thoughts on the matter. (See the Contact page on this site to send us a message.)
Meanwhile, we can all be mad at Amazon for not making clear which devices are suitable for print replica ebooks.
And oldsters can be nostalgic for the days when no one would have tried to read a book on a phone.
