La espada del tiempo

Los mitos vikingos son reales. Los dioses de Asgard están preparándose para la gran guerra. Trols, gigantes y criaturas horrendas se entrenan para el Tagnarok, el fin del mundo. Magnus tendrá que viajar por los nuevo mundos en busca de la única arma que puede detener el Ragnarok --una espada legendaria perdida hace miles de años-- y en el camino tendrá que tomar la más dificil de las decisiones. Porque a veces, para salvarse, es necesario morir.

Magnus Chase has always been a troubled kid. Since his mother's mysterious death, he's lived alone on the streets of Boston, surviving by his wits, keeping one step ahead of the police and the truant officers. One day, he is tracked down by a man he's never met -- a man his mother claimed was dangerous. The man tells him an impossible secret: Magnus is the son of a Norse god. The Viking myths are true. The gods of Asgard are preparing for war. Trolls, giants, and worse monsters are stirring for doomsday. To prevent Ragnarok, Magnus must search the Nine Worlds for a weapon that has been lost for thousands of years. When an attack by fire giants forces him to choose between his own safety and the lives of hundreds of innocents, Magnus makes a fatal decision.
