Compared to his other ones I can't really say what this book is specifically about - there's A LOT about scepticism, the usual anecdotes from readings and live shows, some thoughts about meditation and some notes from his friends and family. That, especially, was a nice touch. I do have to say that this book had more of a negative vibe than the other four just because it was dealing so much with sceptics but that's okay because it's a very real aspect of Kelvin's life. It may also be to do with the fact that he had a different co-writer only for this book and I guess she brings with her a different outlook. #bringbackmargie
Now that I've read all of his released works I can say that they're worth the read, some stories and stuff get repeated a couple times across different books but there's still enough from each other to all be interesting.
