The Book Blogger Hop is hosted by Jennifer at Crazy-for-Books!
It's a little of both really. While I'm reading I think of things I definitely want to include and I even write them down in this 'idea book' I have, but when I'm really writing a review I don't feel like it's fair to actually sit down and write it with out having read the book all the way through. The things I write down ahead of time are things like, "I love that it's funny! Lend = awesome!" <--- exact quote taken during reading Paranormalcy, and another one was, "Music and voice are amazing!" <--- while reading The Mockingbirds.
So now you know how strange my notes are, but that's really how my reviews go. I collect all of the little note feelings and then sit down to write my review.
