Slag. Noun. A promiscuous woman, of cheap or questionable character. Mostly derogatory. Sometimes affectionate. Once a slag, always a slag? Sarah is 15, obsessed with boys and sex and getting drunk on Malibu. Most seriously of all, she's obsessed with her teacher Mr Keaveney. Sarah is 41, the last of the party girls. But even for her, the mad nights out are losing their shine, and there's hardly anyone worth sleeping with anymore. Instead, Sarah and her sister Juliette are going on a whisky-fuelled campervan trip across Scotland to celebrate Juliette's birthday. They haven't always got along, but they both know how the deep, dark, mortifying secrets of your teenage years can haunt you forever. And it's time to dig up some demons. From the acclaimed author of Animals and Adults, Slags is a no-holds-barred, frank and heartfelt exploration of sisterhood, friendship and teenage obsession.
