Another cached US Kindle giveaway: 6 copies of Isaac Asimov's THE END OF ETERNITY, his attempt to make a time travel novel. (His story about the chemical was much better.) I read this while I was in high school, and I wonder what I would think of it now. (I have a copy so I can find out. What do you think, @jdnicoll?)

As always, feel free to claim one, or tell other people about it, or both! And remember to tell your pets you love them.
