Continue reading sits at the top. Underneath come the rails your server already offers: recently added, unread, your series in order.

Search the whole library, with your recent searches kept.

Shelf follows your phone's light and dark setting, and the reader has light, sepia and dark pages of its own.

EPUB, PDF and comics open in a built-in reader. Paged or scrolling, in light, sepia or dark, with type you can adjust, including a font made for readers with dyslexia. Your place is written back to the server.
Downloads stay on your phone, so a book opened once reads on the plane. Progress made offline is sent when you land.
