This post about ebook reader and management apps is presented by BookFusion.

If you love reading, BookFusion may be the ideal app for you. It allows you to have your entire ebook collection at your fingertips on any device you own. You can easily upload, organize, sync, read and share ebooks across all your devices.

All that, and the reading experience is pretty great, too. In fact, you can replace apps like Marvin 3, Kybooks and Calibre Companion with just one iOS app — BookFusion.
