THE SUNDAY TIMES BESTSELLERNIGEL - One of Britain's favourite dogs! MONTY DON - One of Britain's favourite presenters. When Monty Don's golden retriever Nigel became the surprise star of BBC Gardeners' World inspiring huge interest, fan mail and his own social media accounts, Monty Don wanted to explore what makes us connect with animals quite so deeply. In many respects Nigel is a very ordinary dog; charming, handsome and obedient, as so many are. He is a much loved family pet. He is also a star. By telling Nigel's story, Monty relates his relationships with the other special dogs in his life in a memoir of his dogs past and very much present. Witty, touching and life-affirming, Nigel: My family and other dogs is wonderfully heart-warming. Monty Don is a great writer coming out of the garden and into the hearts and homes of every dog lover in the UK.'I have always had a dog, or dogs. I cannot imagine life without them. I am just as much a fan of Nigel as any besotted viewer. In the book I explore why we love dogs and what they mean to us emotionally and domestically. I look back on all the dogs in my life - all of which I have loved deeply and which have been an essential part of my life. So, this is the book of Nigel - but also the book of all our dogs in every British family and a celebration of the deep love we feel for them' Monty Don

An edition and English translation of the Speculum Stultorum (The Mirror for Fools), a long Latin beast epic written near the end of the twelfth century by a monk of Christ Church, Canterbury. This was one of the most popular works of the Middle Ages, a favourite of Chaucer, Gower, and Henryson, and was copied for over three centuries, with a circulation extending as far as eastern Europe. It is not only a milestone in the history of medieval beast epic, but a rich source of information about contemporary life and events at Canterbury. The work is dedicated to William Longchamp, who was Richard I's chancellor, and the significance of this fact is shown. This is a highly entertaining narrative about a donkey who longs to have a longer tail and journeys to Salerno to buy some (imaginary) medicines which will provide it. When his medicines are destroyed in an accident, he decides to become learned instead, and goes off to study at the university of Paris for seven years, but can still say only 'heehaw'. Interwoven into this simple narrative are other stories and long rhetorical set-pieces which satirise the distorted values of contemporary religious life or the corruption of the papal curia, and describe the qualities of an ideal bishop (which the donkey hopes to become).
Nigel the Nit is an intrepid adventurer who wants to explore, but his friends and family just want to stay put. This is the story of his journey to a series of strange new hairy worlds.
