I love these questions!
1. What was your favorite book during childhood?
So many to choose from! The Little House series by Laura Ingalls Wilder is the first one that comes to my mind, and for good reason, now that I think about it. I read those books over and over again. I loved them all, but my favorite was Farmer Boy, about when Almanzo was growing up. Maybe it was the descriptions of ALL. THAT. FOOD. That, and the description of his friendship with his sister Alice and his sibling rivalry with his sister Eliza Jane.
2. What is your favorite book now?
I'm going to borrow
spikesgirl58's answer and say it's usually 'whatever I'm reading at the moment.' I am enjoying Neil Gaiman's new collection of stories, Trigger Warning. As usual, it's kind of a mixed bad, and I don't love everything in it, but the good stories are really good, and the so-so stories are still all right.
3. What is your favorite movie adaptation of a book?
Easy -- 'The Shawshank Redemption,' based on the Stephen King novella Rita Hayworth and the Shawshank Redemption. It's one of my favorite movies anyway, but it's also a fantastic adaptation of the novel. The only thing missing is the "Oh shit, it's shit!" line. :-)
4. Do you prefer checking out books from the library or buying them?
I'm frugal enough to *LOVE* the library, otherwise I would spend a fortune on books that I would turn out not to like. But thanks to the library I take all sorts of chances on reserving books that I'm not sure of and discovering authors that I really enjoy.
I've learned to treat myself to buying myself books more and more often, though. (What I need to do is buy myself more spare time to actually read them!
5. Have you ever been let down by a book that was highly recommended to you?
Not that I can think of. There's a fair amount of books that I give up on after a couple of chapters (or less, if it doesn't grab me in the right way), but I don't know if I feel *let down* by them. It just wasn't the right book for me.
