The Wild Places by Robert Macfarlane
Its about finding 'wild places' - sometimes in unlikely places and is fantastically well written.
As I recall, he uses words I didn't know but somehow it all made sense. May be worth having a dictionary handy if there is something you really must have the exact meaning of. I may be making it sound as if it is heavy going - but it definitely isn't. If I don't enjoy a book I just stop reading it - life's too short to continue reading something you don't enjoy. This is one of the few books I actually remember having read, and might even read again - something I have never done before
