Cara Delevingne is living the dream. Signed by Storm Models founder Sarah Loukas - the same woman who spotted Kate Moss - when she was just 17, Cara's career has reached dizzying heights. As the face of DKNY, Burberry and Chanel, Cara's startling blue eyes gaze down from billboards across the world.

Known for her irreverent style and kooky sense of humour, Cara is no poster-girl for perfection. Rather, with her thick eyebrows and snubbed nose, she pushes the boundaries of modern-day beauty, embodying the edgy girl-about-town, kicking about with celebs like Rita Ora, Rihanna and Jake Bugg. The granddaughter of English Heritage chairman Sir Jocelyn Stevens, Cara can count Joan Collins and Conde Nast managing director Nicholas Coleridge among her godparents.

But while her roots are far from gritty, it is Cara's wild side that garners the most column inches and makes her a constant source of fascination the world over. In this, the first unauthorised biography of the British beauty, Abi Smith reveals Cara's life behind the lens, exploring just how she manages to be both weird and wonderful.
