She belongs to a kind of club, which involves luxury, beautiful clothes and accessories. The club makes it possible for Kayo to escape her tedious life, to become someone else and to embrace a dazzling new world. But it quickly becomes an obsession, a drug, the way to both paradise and hell. Can she find her way out of the dark underworld of debt, lies and prostitution? Or is she doomed to exchange one form of loneliness for another? A deeply absorbing novel about the "holes" that suddenly appear in women's lives, My Beautiful Shadow is a powerful cautionary tale about consumerism gone mad.
