Seventeen-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, twelve-hour dash around London - starting at 8pm in Crystal Palace (so far away from civilisation you can't even get the Tube there) 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 - from friends, apparent-enemies, famous bands and even rickshaw drivers - is willing to help a girl on a mission to get her romantic retribution.
