Blogger Samantha Clark mentioned in a comment here yesterday that she was able to download the IndieBound e-Reader app to her Kindle Fire. She shares step-by-step instructions as to how to do it on her blog. If you give it a try, let us know if it works for you, too.
Writers, you might want to spend some time clicking around over there, as Samantha’s blog is primarily a place of tips and news for writers.

Thanks for posting, Julie. I was thrilled that I could still support BookPeople with my Fire. Love you store!
Excellent! I got a kindle fire for Xmas, so I just installed IndieBound. I hadn’t wanted a kindle initially because of the restriction about only buying from Amazon but I’m glad I can support BookPeople still!
I got my kindle fire on this Christmas, so I definitely try the app.
Thanks Samantha for your instructions and Julie for share.
So glad to find this out! I just got my Kindle Fire for Christmas! Thank you, BookPeople, for putting the info out there.
