Tal como predijo la astróloga más reputada de San Francisco, una oleada de crímenes comienza a sacudir la ciudad. En la investigación sobre los asesinatos, el inspector Bob Martín recibirá la ayuda inesperada de un grupo de internautas especializados en juegos de rol, Ripper.

"Mi madre todavía está viva, pero la matarán el Viernes Santo a medianoche", le advirtió Amanda Martín al inspector jefe y éste no lo puso en duda, porque la chica había dado pruebas de saber más que él y todos sus colegas del Departamento de Homicidios. La mujer estaba cautiva en algún punto de los dieciocho mil kilómetros cuadrados de la bahía de San Francisco, tenían pocas horas para encontrarla con vida y él no sabía por dónde empezar a buscarla".

ENGLISH DESCRIPTION

Isabel Allende--the New York Times bestselling author whose books, including Maya's Notebook, Island Beneath the Sea, and Zorro, have sold more than 57 million copies around the world--demonstrates her remarkable literary versatility with Ripper, an atmospheric, fast-paced mystery involving a brilliant teenage sleuth who must unmask a serial killer in San Francisco.

The Jackson women, Indiana and Amanda, have always had each other. Yet, while their bond is strong, mother and daughter are as different as night and day. Indiana, a beautiful holistic healer, is a free-spirited bohemian. Long divorced from Amanda's father, she's reluctant to settle down with either of the men who want her--Alan, the wealthy scion of one of San Francisco's elite families, and Ryan, an enigmatic, scarred former Navy SEAL.
While her mom looks for the good in people, Amanda is fascinated by the dark side of human nature, like her father, the SFPD's Deputy Chief of Homicide. Brilliant and introverted, the MIT-bound high school senior is a natural-born sleuth addicted to crime novels and Ripper, the online mystery game she plays with her beloved grandfather and friends around the world.
When a string of strange murders occurs across the city, Amanda plunges into her own investigation, discovering, before the police do, that the deaths may be connected. But the case becomes all too personal when Indiana suddenly vanishes. Could her mother's disappearance be linked to the serial killer? Now, with her mother's life on the line, the young detective must solve the most complex mystery she's ever faced before it's too late.
