Leah McFall: books my friends borrowed and never returned

Writer and reviewer Leah McFall reckons one of the best endorsements for a book is when your friend borrows it and it never comes back. Leah shares three great non-fiction titles currently missing from her bookshelves: Amy Liptrot's The Outrun, Ruth Reichl's Garlic and Sapphires and Craig Brown's One, Two. Three, Four.
