I read most of the book. It's sitting on my desk right now. What's not clear from your post is who you are and if you have read the book. You're free to add your own review if you have a different opinion. :)

It's not "Why can't I spell lets", it's "Why can't I type it?" I make typos like everyone else. Despite what you may think, editors aren't exempt from human frailty. Indeed, I think that's the point of the review.
