Book you keep meaning to read that always gets bumped to second place by new purchases: Tolkien's The Silmarillion. I have started it, but new stuff always pushes it out of the way.
Book you put down halfway through and never got back to: Dreamcatcher, by Stephen King. Although I'll probably pick it back up again soon, hopefully before the movie.
Book you love and can never convince anyone else to read: Winter's Tale, by Mark Helperin. I think I'm asking the wrong people, though. I bet most of you guys would love it. Either that or you've already read it.
Book you'll never read no matter how many people tell you you should: Probably the Outlander series by Diana Gabaldon. I started the first one, and it reads waay to much like a romance novel for my tastes.
Children's book that no-one else remembers except you: The Children Who Stayed alone by Bonnie Bess Worline, an adventureish story of children stranded alone in a blizzard in their home on the prairie in the 19th century. Also Hotel for Dogs, a wonderful, heartwarming story written by Ms. Duncan in her pre-I Know What You Did Last Summer days.
Children's book everyone seems to have read that you've never read / heard of: Charlie and the Chocolate Factory by Roald Dahl. I have absolutely no desire to ever do so, either. Dahl's books are too morbid for me. Never saw the movie, either.
Terrific book, terrible movie: This is a hard one. I'd have to say Hearts in Atlantis by Stephen King. I really didn't think the movie was terrible, though. The problem with this one is that if you haven't read the story the film was based on, you're left a bit lost. Also, the film deliberately left out references to King's Dark Tower series, which were key to the story. Of course, putting those references back in would have confused those who hadn't read the books even more. Eh. Anthony Hopkins rocked, anyway.
Most Overrated / Overhyped Book or Author, in your opinion: Tim Lahaye and Co.'s Left Behind series. It's not the blatant Christian proselytizing that bothers me so much as the terrible writing. I read the first few pages, and blech. It's just bad writing, IMO. I mean, really. C.S. Lewis' Chronicles of Narnia are allegorical almost to a fault, but the writing is lovely.
Most Underrated / Misunderstood Book or Author, in your opinion: This is a question with two answers.
The most underrated Author is definitely Stephen King; even with his immense popularity he's still regarded by "literary" folk to be pretty low-class. I disagree entirely. I think his Dark Tower is turning out to be as good as anything Tolkien ever wrote. I guess he could be (and often is) compared to Charles Dickens, who was dismissed himself by the snobby types of his day.
The most misunderstood book? His Dark Materials by Philip Pullman. The series has been criticised by many as a blatant dump on Christianity in general and the Catholic Church in particular. I disagree. I think the story is designed to make us question those in authority who use God's name to commit atrocities, as well as bring up questions regarding consciousness, love, and self-sacrifice.
