In his book Write To the Point, Sam Leith shows how to express yourself fully across any medium, from work reports to Valentine cards, and from emails of condolence to tweets of complaint, Leith lays bare the secrets to successful communication, eloquence and off- and online etiquette. Emma Byrne's book Swearing Is Good For You is a spirited and hilarious defence of our most cherished dirty words! Swearing, it turns out, is an incredibly useful part of our linguistic repertoire. Not only has swearing existed since the earliest human communication, it has been shown to reduce pain, help stroke victims recover their language, and encourage good teamwork.
