About Starting Chapters at The Top of New Pages (Screens):

Creating chapters and page breaks is very easy, and it’s strongly encouraged that you use them. The break in the flow of paragraphs helps the readers “feel” like they are reading a “real,” or print, book.  Some retailers of ebooks have books that have a chapter starting right after the one before.  The location of a Chapter title at the top of the screen, or "page," helps the reader channel the sense of the print version of the book.  Below is the first chapter of "Requiem for the Puppet Master" from an Amazon Fire tablet, and you can see how starting the chapter at the top of the screen really makes the book feel like a book.
