I don't know if you've ever felt this way, but sometimes, after I've read a book (or watched a really good movie), it just fills up my mind. I don't want to let anything else in to take its place for a while. Not another book. Not a T.V. show. It's just my thoughts about the book and me. I want to savour the thoughts and feelings that rise up when reading a really great book.
My most recent read The Ask and the Answer by Patrick Ness was like that for me. I didn't like it at first, but I'd read the first book in the trilogy, The Knife of Never Letting Go, and I was hooked on the characters. So I carried on with it. Wow - did it get me. It stirred up so many emotions and made me think. Even when I wasn't liking it, I couldn't put it down.
