I'd heard this book was somewhat controversial as it attempts to dispel some of the heroic myths the British have bestowed on WW2.
I don't know if it's because I'm particularly well versed on this period of history, but I found this not in the least controversial.
However, I'm pretty sure there's still a sizable portion of the public that have a rather rosy image of those catastrophic years, but I can't help but think this was probably necessary to keep the country functioning during a period of rapid decline.
Peter Hitchens writes well and is easy to read. If you are not a student of history and want to understand the real history of WW2 as opposed to the Hollywood version, then I'd recommend this book as a good launching point to widen your knowledge.
