In The Guns of Santa Sangre, three 1800s gunfighters battled a ferocious pack of werewolves in Old Mexico. In the sequel, The Wolves of El Diablo, the three outlaws rob a Federale steam train in the badlands of El Diablo transporting a fortune in silver bars. But when a savage werewoman, hungry for revenge on the men who killed her brother, leads her bloodthirsty gang of wolfmen in an attack on the train, the outlaws find themselves trapped on a highballing railroad in the middle of the desert fighting fifty werewolves.
This time it's bigger action, more lycanthropes, more silver bullets, and much more Werewolf Western thrills
"In this blood-soaked weird west story (following The Guns of Santa Sangre), bad guys come with glowing red eyes instead of black hats, but they still go down in a hail of (silver) bullets. Red mixes up vengeful werewolves, roguish American outlaws, and Mexican peasant Pilar, whose love for gunman Tucker leads them to embark on a train robbery. Tucker and his buddies Fix and Bodie haven't been paid for a previous werewolf encounter, so they plan to heist the silver shipment from the Salazar mine. Azul, sister to slain werewolf leader Mosca, wants them dead, and stolid Colonel Higuerra and his 60 federales are not letting the silver go without a fight. Red, a screenwriter as well as a novelist, places a premium on action ("Then the first of the three werewolves struck!") over character or description. Readers will enjoy discovering the connection between Azul's abandoned twin pups and the mysterious, hypermasculine Salazar brothers and appreciate the resolution of Tucker and Pilar's story."—Publishers Weekly
