Just wanted to send everyone to look at a recent "The Big Idea" post by John Scalzi. Various authors write about their recents releases, usually with some really interesting background about their inspiration.
This one: The Big Idea is about Merrie Haskell's The Princess Curse, which stems from some of her own fears, and loves.
Check it out. I am going to be on the lookout for it when I next go to a bookstore.
