This app uses a strange method of pagination. Each section/chapter of the book is a single long page, which you scroll up and down through. When you get to the end of a section, it jumps you to the beginning of the next section -- even if your finger is still on the page because youre reading whats left of the previous section.
Since these books are not available in electronic versions elsewhere, or in formats like DRMed PDF, users are stuck with this terrible interface.
Please allow for standard pagination in the next version of this app.
