Book excerpt: Duarte's latest novel is based on a string of real-life murders in Ciudad Jurez in the 1990s. Forced out of the house by her alcoholic mother, 13-year-old Evita takes to the streets, glimpsing newspaper columns about the murders, while struggling to survive. Petra, Evita's comely 19-year-old cousin, exchanges the country life for gritty Jurez to raise money for her ailing father.
