After centuries hiding away in coffins, forests and ram-shackled dens, the vampires, werewolves, witches and warlocks are now living secretly among us. This is the story of Jack Celby, the hormonally charged teenage son of vampire parents, who lives on Felicity Street or Fiend Street as it is affectionately known to many of its residents, as over half the population living there are descended from those who sucked blood, howled at the moon or stirred their stinking concoctions in steaming hot cauldrons. All is not well on Fiend St. Although Jack, his parents and all the 'irregulars' have successfully assimilated into normalised society, they now face a terrifying battle against the mongrels, a blood-thirsty race created from the poisonous union of deviant vampire and werewolf blood. The disciples of the Black Coven of Windermere have been summoned to exact a swift and bloody revenge over a heinous incident. A young werewolf child has been kidnapped, perhaps even slaughtered, and all the witches' cats have been horribly mutilated in a barbaric attack that can signify only one thing: the mongrels are uprising and no one is safe, especially Makayla, Jack's mongrel girlfriend.
