So I logged onto the email I use for my Amazon/Kindle account, and saw I had an email that said someone had gifted me a book! I guess there is sort of an underground thing where you can look at people's wish lists, that are set to public, which I guess mine is, and if you want, gift someone a book on their list! I was so surprised, and it happened to be one of the ones I really wanted to read, and probably would have bought, once I figured out how much I want to spend on my next Kindle buying spree!
So thank you to the anonymous gifter - you made my day! Now I need to figure out how that works, and I'll go and gift something myself!
