I came to this after reading McCann's first novel Nailed - Digital Stalking, a fantastic, fast moving thriller based on real events but not, if you know what I mean.
This was quite a shock, it's completely different. A very funny, coming of age tale full of colourful characters and situations.
Rick your review almost put me off but I think you've completely missed the point of the book, you should have re-read it. For example, you said Bowie put him down and that the `arrogant' author must have been very embarrassed. Bowie didn't say anything, it was the author imagining what was going through Bowies head, he put himself down which kills your point. There's more but I think the author is laughing with us at his young over-confident self.
Although it was nothing like what I was expecting, I loved this book, it took me right back to my silly teenage self, made me feel young again and the picture it paints of the seventies is a joy.
