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 with their human families in Rome, they unwittingly discover and then must end a centuries-old global war between cats and dogs. They join forces with Friskie, an affable mutt they encounter in the Roman Forum, and also enlist the support of a feisty band of feral cats. Above all the action looms Prudens Poorchie, a ghostly Pomeranian who forecasts a disastrous outcome if Harley, Angela and Friskie don't succeed in their mission.
