England - The Hitch-hiker's Guide to the Galaxy - Douglas Adams

It doesn't get more English that THHGTTG, with a dressing gown wearing, tea drinking, petty minded protagonist.

Everything about this book screams it's English heritage and culture. I'm a huge fan of Douglas Adams and the trilogy of five books that this grew into. This a funny book full of slapstick silliness, clever satire, puns, profanities, sarcasm and pretty much every type or humour going. The sci fi side of the book makes the perfect setting to marry so many ideas and thoughts and I LOVE IT!
