This book is a work of fiction but is portrayed as a memoir about a man, just deceased, and his somewhat odd affections for a donkey called Caroline.
He meets the donkey whilst on holiday, buys it and takes it home where he spends all his time with her, even taking her to his workplace and teaching her chess, which the donkey always seems to win.
The text is interspersed with photos, article cut-outs and so on that the deceased man collated/wrote which supplement the story (or to get in the way of the story perhaps?).
For me the writing style was very formal (e.g. the man is known only as Mr. Shaw or Shaw) as if the story is less a story and more an outlining of facts. So it was a little hard to read, plus there wasn't much of a story to tell either. So I can't really recommend it. Instead you could try Pyg by Russell Potter, which is another memoir about a remarkable animal, written in a sort-of old-fashioned style, not totally dissimilar to the style of this book but easier to read, and a better story.
(I got this book for free to review through Amazon Vine. It is listed here.)
