I've seen this book mentioned a few times on this forum - is it worth getting?

I'm in the UK and so ride on the left, I could imagine it might get annoying as I guess everything is written from the US point of view.

I have been riding on the roads for about 10 years and would consider myself a reasonably experienced (though by no means perfect!) cyclist. So does this book have enough advanced, in-depth information to make it worth it for me?
