I downloaded the Kindle app to my [spoiler]Windows[/spoiler] phone.
On Amazon, there are free books.
The 1st one I read (and again, it's a phone, not an ereader nor tablet), when I swiped the page, occasionally a few (or more) words seemed to be missing; eg., the text might say, "She sells sea", but, swipe page, and first text would be ".....Wizard of Oz" (yes, being facetious).
But, the book I'm currently reading, Seasons Blood; Midnight Harvest is fantastic.
I don't know the end.....but it would be 'akin' to stuff on DS...
