About This Book
The soft rustle of litter fills the air as a curious tomcat pads into the room, his fur rough and wild. But this isn’t just any cat—he talks, saying he’s a great-grandpa with a secret mission that only you can help with. Suddenly, the ordinary feels magical, and family ties reach across time.
