Apparently Child of Fire is available in the Google ebook store. They even have sample pages from the beginning of the book. If you look at it as “scanned pages” (iow, laid out the way the printed book is) you can read up to page 37. If you set the sample to “flowing text” you can read a little farther, and can change the font, font sizes, and line spacing too. It’s pretty nice. I haven’t had the opportunity to read a book on an ereader; is this what it looks like, usually?
Interestingly, Game of Cages isn’t available for sale there. I’m not sure why. Maybe it just takes time to load the books in.
