The Book of Other People is just that: a book of other people. Open its covers and you'll make a whole host of new acquaintances. Nick Hornby and Posy Simmonds present the ever-diverging writing life of Jamie Johnson; Hari Kunzru twitches open his net curtains to reveal the irrepressible Magda Mandela (at 4:30a.m., in her lime-green thong); Jonathan Safran Foer's Grandmother offers cookies to sweeten the tale of her heart scan; and Dave Eggers, George Saunders, David Mitchell, Colm Toibin, A.M. Homes, Chris Ware and many more each have someone to introduce to you, too.
