Sorry, I should have put more information.
It's not a PDF. Tor's download options are PDF, Mobipocket, HTML, and epub. Since I have a Sony 505 I chose epub. The formatting is good. The text is flowing normally. It's not displaying partial screens the way PDFs do when you reach the end of a page. (That is so frustrating.) I wouldn't have known it wasn't .lrf from reading. It's just the page count that threw me. Especially when the number indicated it was spanning two pages and there was no obvious page break in the text.
Llasram (or anyone else), what is an internal file boundary? Is that what made the cover one page and the illustration one page? One "page"="1K of text" gives me a basis for estimating the length of a story or book. Thanks!
