I thought this book was OK, but slightly off. I could deal with the fact that he talked to Tony Hawk, because I can kind of see that happening to a teenager. And the plot isn't difficult to follow or anything. But the part where he jumps into the future and jumps back? That threw me off. Especially when things turned out the same way. I would have preferred if he jumped into the future once, but it wasn't actually like that. Like the jump was just a dream or something.I don't know. I love Nick Hornby's writing style so I didn't mind this book. The majority of it was good, but that last bit just really bothered me.
