Who's Whose?: A No-nonsense Guide to Easily Confused Words

I borrowed this book from my local library after some deliberation as to whether or not to buy it, and I'm quite glad I only borrowed it. An entertaining read, guaranteed to make you say "wow I never knew that", however due to people simply using the internet to look things like this up I cannot imagine anyone using it as much of a reference book, therefore if you can get it from somewhere like a local library, I would recommend this instead. Having said that, I find it more of a fun and light-hearted read that many other books like this (Mind The Gaffe for example), so worth a read.
