here. I scrolled through my own books and was surprised to see that many of them were lendable. Of course, the free ones were, since they're in the public domain, I wasn't surprised about that. But many of my newer YA books were also lendable.
The loan period is for 14 days to only 1 person. When you grant permission, Amazon will email the person and let them know the book is available. The coolest part is that you don't have to own a Kindle! Remember that the Kindle app is available for virtually any digital product here. (Yeah, I should really be getting paid by Amazon, but sadly, I'm not!)
While the book is checked out, you cannot read it. This makes sense. If you lent out a physical book, you couldn't read it during that time, right? Also, if you were able to loan out Kindle books to as many people as possible, then the publishers/authors, etc. would be losing money. We want to keep the authors writing and publishing all the books we love.
So, hats off to Amazon & Publishers for allowing this lending feature!
