Thanks to Girl with her Head in a Book I found out about Flirting with French. This book is written by a guy who is trying to become fluent in French in his 50's. It is quite hilarious while at the same time being really true – in my experiences with trying to speak French anyway!
I recommend this book for anyone who likes France or who is trying to learn any second language. It will give you a reason to continue your efforts – but to avoid spoilers, I won't tell you what it is.
You will also learn some other fascinating stuff along the way – like how come English avoided having all words belong to a gender? And why we don't have the formal and informal words for you – ie vous and tu.
I found the book very enjoyable and devoured it in a couple of days.
