When Tessa Torrance, newly minted royal and wife of Prince Dante, becomes the target of a suspected assassination attempt, her mother's first instinct is to ask Tessa's old friend Odelia Poole to track down the would-be assailant. Odelia, Chase and Odelia's grandmother are flown over to England and move into Newtmore Cottage with Tess and Dante. They soon find themselves in over their heads when the hits keep on coming and things get very hairy indeed.

Good thing Odelia's cats have traveled along with her to the Land of Hope and Glory, in a bid to lend support to Tessa's English bulldog Fluffy. All the cats can think of, though, is meeting those most famous pets of all: the Queen's corgis. But when Gran gets it into her nut that she wants to be Queen of America, things quickly spiral out of control.

Will Odelia and Chase be able to save the Duchess of Essex from certain death? Will Gran become America's first Queen? And if that's the case, who will be First Cat? Find out in Purrfectly Royal, Max's most regal adventure yet.
