On their wedding day, Shara and Bear Grylls asked guests to each give them a piece of advice about marriage.   To mark 25 years together, the friends they've met along the way have contributed to this new edition. Olympians and Oscar winners, comedians and chefs, aristocrats and artists are among the many friends joining in the fun. Ideal for those just beginning, and for those with many years together. This collection will inspire, amuse and celebrate the journey of marriage!
