The Windows 10 Store will soon offer e-books, and the guys at MSPowerUser have managed to get some screen shots of an internal build of the Windows 10 Mobile that shows off the feature.
The screen shots advertise the ability to buy and read e-books from the Store, this follows Microsoft Edge browser introducing support for epub documents in build 14971 of Windows 10. According to MSPU:
We were today able to get an early look at the new e-books store in an internal build of Windows 10 Mobile… Once purchased, you can start reading the book on Microsoft Edge which is also getting a dedicated section for Books in Windows 10. This is where you will be able to find all the books you have purchased from the Windows Store which is pretty neat. Thanks to Microsoft Edge’s strong EPUB support, you will be able to add bookmarks into any book you are reading or easily view the table of contents. You can also customize the EPUB Viewer’s theme, change the font size and even the font family to fit your needs.
