Ager Aguirre (Basauri, 1975) is the author of ‘El Monasterio de Piedra’, a thriller set in the Monasterio de Piedra park (Zaragoza), a paradisiacal setting in one of whose caves a corpse appears. A team from the Civil Guard, with Agent Gallur and Agent Dávalos, will lead the search for the murderer.

According to legend, the Monasterio de Piedra park emerged after a battle between angels and demons, a fight in which the forces of good won.
