When someone takes a shot at well-renowned pop star Charlie Dieber and kills one of his bodyguards instead, Odelia Poole, self-confessed Bedieber and big-time fan, is quick to offer her assistance to help find the shooter. Teaming up with Detective Chase Kingsley, she enters the world of the Dieber, and soon discovers not everything is as it seems.

Odelia's cat menagerie, meanwhile, is in a state of shock when longtime rival Diego returns to Hampton Cove, and immediately starts stirring up trouble. Diego has one goal in mind: take over Max's place in Odelia's home and heart and get Max, Dooley and Brutus sent to the pound. The only one who can help them is Clarice, their feral friend. She got rid of Diego once, and they hope she will do it again. Unfortunately Clarice has been adopted. By Charlie Dieber.

Will Diego become Odelia's new go-to feline sleuth or will Max strike back? Will they be able to stop the killer before he kills the world's number-one pop star? And will Grandma move to Washington and go into politics? Find out in Purrfect Rivalry, a cozy cat mystery like no other.
