17-year-old Sunny’s always been a little bit of a pushover. But when she’s sent a picture of her boyfriend kissing another girl, she knows she’s got to act. What follows is a mad, 12-hour dash around London – starting at 8pm in Crystal Palace then sweeping through Camden, Shoreditch, Soho, Kensington, Notting Hill, and ending up at 8am in Alexandra Palace. Along the way Sunny meets a whole host of characters she never dreamed she’d have anything in common with – least of all the devilishly handsome (and somewhat vain) French ‘twins’ (they’re really cousins) Jean Luc and Vic. But as this love-letter to London shows, a city is only a sum of its parts, and really it’s the people living there who make up its life and soul. And, as Sunny discovers, everyone is willing to help a girl on a mission to get her romantic retribution.
