Neglected by her parents, nineteen-year-old Maya Nidal has grown up in a rambling old house in Berkeley with her grandparents. Her grandmother Nidia, affectionately known as Nini, is a force of nature—willful and outspoken, unconventionally wise with a mystical streak, and fiercely protective—a woman whose formidable strength helped her build a new life after emigrating from Chile in 1973. Popo, Maya's grandfather, is an African American astronomer and professor—a gentle man whose solid, comforting presence helps calm the turbulence of Maya's adolescence.When Popo dies of cancer, Maya goes completely off the rails. With her girlfriends—a tight circle known as the Vampires—she turns to drugs, alcohol, and petty crime, a downward spiral that eventually bottoms out in Las Vegas. Lost in a dangerous underworld, she is caught in the crosshairs of warring forces—a gang of assassins, the police, the FBI, and Interpol. Her one chance for survival is Nini, who helps her escape to a remote island off the coast of Chile. Here Maya tries to make sense of the past, unravels mysterious truths about life and about her family, and embarks on her greatest adventure: the journey into her own soul.
