Cached US Kindle giveaway: 10 copies of @maryrobinette's THE CALCULATING STARS. Which, I bashfully admit, I haven't read! But people whose opinions I trust deeply say they're *great*. And she's a Hugo nominee this year, even though I don't have copies of that one to give away. Sorry.
As always, feel free to claim one, or tell other people about them, or do both! And talk about the book if you read it!
