Fifteen-year-old Mélanie drives across the Arizona desert in a white Meteor, chasing fear and desire and the mysterious Angela Parkins, and breaking free from her mother and her mother's lover in their roadside Mauve Motel. And then we are with Maude Laures as she reads Mauve Desert, this story of Melanie, and becomes obsessed with it. She embarks on an extraordinary quest for its mysterious author, characters and meaning, which leads us into the third part, Mauve, the Horizon, Laures's eventual translation of Mauve Desert.
