Set against the backdrop of 1840s Mexico amid the tensions with Anglo settlers, 'Vampires of El Norte' is a supernatural western penned by Isabel Caas. Nena, a rancher's daughter, is all too familiar with monsters that threaten her home. But the terror grows as she faces beings that drain men of their blood, the same creatures that once attacked her. The United States' invasion of Mexico leads to Nena crossing paths with Nstor, her childhood sweetheart who she believed had abandoned her after a nightmarish encounter. Reunited under the shadow of war, Nena, a determined healer, and Nstor, a drink-tormented vaquero, must confront their harrowing pasts if they wish to outlive the horrors that the night brings. Their survival hinges on facing the darkness together, but can their rekindled bond withstand the bloodthirsty truth waiting to be unveiled by dawn?
