Whether they are black dogs, pale horses or birds of ill omen, certain animals have always maintained a deep connection with the Beyond, terrorizing mankind since time immemorial. In these pages we will follow in the footsteps of messenger dogs of death, nocturnal howlers, custodians of cemeteries, beasts from beyond the grave, emissaries of storms, escorts of the devil and guardians of the underworld. From the hand of Israel J. Espino, author of the bestseller Gente de muerte, we will ride on fearsome spectral horses, aquatic monsters and flying equines, we will see fire nags and headless creatures. We will behold, in awe, ghostly chariots that soar through the skies and wagons of death that still rattle along ancient paths of old Europe. We will discover the hidden language of the night songs and learn to interpret the supernatural voice of the birds of death: the sinister whistling of the crows, the eerie hooting of the owls and the haunting cry of the owls. We will travel thousands of miles together in the footsteps of the beasts of death, discovering ancient sacrifices and collecting modern testimonies, and we will understand that, after all, they are there to show us the path that, sooner or later, we will all take.
