I've just finished "Cycling Back to Happiness" by Bernie Friend. It's a touching story of someone battling mental illness and how cycling proved the best therapy. He rode the southern half of the North Sea Cycle Route. I've added it to my list of places to cycle. I've driven some of the route in my 2CV van, but now I want to go back under my own steam.
I've also just finished "The Full English" by Mike Carden. It's an altogether lighter read about a mid-life cycle ride up the backbone of England.
