LIFE OF A CHALK STREAM by Simon Cooper
It all depends; if you are looking for great literature, poetic prose, something to impress the intellectual spirit, then Life of a Chalk Stream is not the best place to start. If you are looking for enlightenment, a window into a different world and the passion of one man for his métier, then read this book.
It is clearly written from the heart. The structure is prosaic but you understand completely where he is coming from. It makes no demands other than to enjoy the world the author enjoys and to take you through his delights with an invitation to share.
