A bookworm's best friend
Book Reader for BlackBerry 10 allows users to flip through DRM-free e-books in EPUB, MOBI, FB2, TXT, and CHM formats. Readers can bookmark passages, adjust text size, and switch between light and dark themes for ideal visibility.
Different skins can add a degree of style to your reading experience, plus sensible tap zones allow readers to easily flip through whatever their reading. Screen orientation can be locked from within the app, which is perfect for those of us that like to do our reading in bed.
