This was a hard question to answer. But I'm going to go with the "Conversations With God" trilogy by Neale Donald Walsch. Christians and other members of the popular religions tend to have warped conceptions of God, so they should all read this to hopefully open their mind to other conceptions of God. A great many atheists also tend to be familiar only with the warped version of God, and so should read it so that, at the very least, the angry anti-theist types might loosen up towards people like me who are theist but do not subscribe to the twisted version of God. And even ignoring the bits about God and souls, the CWG books are chock full of interesting advice, possible solutions for modern problems, and other ways of looking at things that are very thought-provoking even if you don't believe the mythological parts of it (and remember, Alex has read these books too and endorses them even though he's a LaVeyan Satanist). They're also chock full of puns, too, and I love puns. :-D
Day 09 – Best scene ever
I can't pick just one! But if I had to, well... There's this one scene in one of the books of "The Neanderthal Parallax" series by Robert J. Sawyer. I don't remember which book, but either 2 or 3. First, some background: "The Neanderthal Parallax" involves an alternate universe where Neanderthals became the dominant human species, and our species went extinct. Two Neanderthal scientists are working on a quantum computer, and when running the first test, it accidentally sends one of them to our universe. Now to the scene: This Neanderthal scientist befriends a human female scientist named Mary. In fact, they're kinda doing the interspecies romance thing, or would be, except Mary has some issues with men because she was raped some time ago. I don't recall all the details, but the Neanderthal scientist guy finds this out, and unbeknownst to her, goes off to find her rapist. Now, the rapist is someone she works for (and I don't remember if she knew this or not), and Sawyer does a really good job of showing us what a slimeball this asstard is. He's not very apologetic even when faced with an angry Neanderthal scientist breaking into his house and tying him up. But he gets his comeuppance. The Neanderthal guy decides to do to the rapist what his people do to rapists: he castrates the guy. Then, punctuating the message, he says something along the lines of "I'm going to make you feel what it's like to be [a woman/one of your victims]," and ASS-RAPES THE GUY! I was laughing like a deranged hyena for 20 minutes at that! I love it when bad guys get what's coming to them.
Day 10 – A book you thought you wouldn't like but ended up loving
This is easy, since there's only one. "To Kill A Mockingbird" was assigned in English class, and since all I ever read back then was fantasy and scifi and survival tales like "White Fang," I refused to read it. But the tests and stuff about the book in class were such a huge part of the grade, and Mom worked at the school (and thus had conversations with the English teacher), she pushed and pushed me to read it. I finally did, on a visit to Cumberland, walking around the town with my nose in the book. I have never liked being assigned reading projects to begin with, and a book from the 60's taking place in The South? I was sure my brain would be screaming at the levels of stupidity, ignorance, and so on of such a book. But I was pleasantly surprised that it was really good.
