I enjoyed the TV series and loved this book. It's split up into lots of interesting bite-sized chunks so there is never a feel of getting bogged down. Covers the origins of languages around the world and how they have evolved; lots of snippets about slang and it's uses, where we get some of our well known phrases, great orators, writers, libraries - there is much to learn!
Strangely, because I had seen the TV series before I read the book, I imagined Stephen Fry narrating the text (and felt I heard his voice within it!!) and yet the foreward is actually the only part by Fry. Spooky - but fun.
