This novella for middle grade readers (ages 8-12) features Harley, an adventurous and charismatic black cat, and Angela, his beloved feline companion. On vacation in Rome, they unwittingly discover and then must end a centuries-old global war between cats and dogs. Mysteries and magical moments abound, but they join forces with Friskie, an affable mutt they encounter in the Roman Forum. They must also enlist the support of a feisty band of feral cats. Above all of the action looms the ghostly figure of Prudens Poochie, a Pomeranian who forecasts a disastrous outcome for dogs and cats worldwide if Harley, Angela and Friskie don't succeed in their mission.
