The bug of eReading has bitten an entire generation. We’re people who read online, flick pages by taps, not fingers and have a flush of portable devices to help us do the same. That being said, it’s definitely a good time to discuss apps you can download on your Windows devices to read ebooks.

These apps are perfectly equipped with everything it takes to run ebooks on Windows desktops, tablets and mobile phones. As reading needs leisure the most, these apps have a clear, tappable interface, allow highlighting and bookmarking, and sync ebooks across multiple devices for anytime access on any device you’re holding at that given moment.
