A book that makes you laugh.
Certainly all-time favourites for quiet chuckles or loud laughter are absolutely all books written by
James Herriot
I've on more than one occasion found myself braying with far too loud laughter in public places when I had his books along.
I also laughed my way through:
"Tangled" by Emma Chase
"A Year In the Provence" by Peter Mayle
"Moab Is My Washpot" by Stephen Fry
