That's my favourite fishing book as well, its quality. 2nd Favourite is probably Terry Hearn's "In Pursuit of the Largest".
My favourite non angling book is probably Howard Marks' "Mr Nice".
One of the funniest books I've read is "The Raymond Delauney Emails" which is full of wind up emails to various people and companies.
Got to just love Mr Nice, Howard is a star! Can't wait for the film to come out, sure Rhys Ifans will do him proud
