Yesterday, Lydia Quixano Perez had a bookshop in the Mexican city of Acapulco. Yesterday, Lydia was married to a journalist. Yesterday, she was with everyone she loved most in the world. Javier Crespo Fuentes was once her friend. They talked about books, shared their secrets, formed a close relationship till one day Lydia's reporter husband Sebastian wrote an article about Javier, the "jefe" of the newest drug cartel that has gruesomely taken over the city. When the article is published, none of their lives will ever be the same. Now, her eight-year-old son Luca is all she has left. For him, she will carry a machete strapped to her leg. For him, she will leap onto the roof of a high speed train. For him, she will find the strength to keep running.
