I thought I'd check out this book for my wife to read to our kids. I loved it. Great little stories joined together and great pictures. I've decided I'll be the one to read it to them.
I would classify this under psychological thriller. It's one of those stories that scares the hell out of you and you don't know why.
As James Jenkins said 'just a chunk in the middle', if you had a beginning and an end (sometimes boring) then you'd understand EXACTLY what was going on. The passengers on the plane didn't know what was going on, that's what made it a good story.
