buy the book
My favourite way for you to buy the book is: go to your local independent book shop. They are a vital part of life, and too many are succumbing to the online buying trend. Many book retailers now offer an online service too - if you can't get to the shop, do that.
The ISBN is 978-1533007261.
You can of course buy it from Amazon or (in the US) Barnes and Noble.
