Packed with high stakes mystery and tons of heart, this first installment in a new series introduces Kazu Jones-a spunky, scrappy detective who's this generation's Harriet the Spy.

When a string of dognappings grips her Denver neighborhood, Kazu Jones vows to track down the culprits. She can't stand to see more dogs go missing-especially once her neighbors' beloved pet is taken because of her gigantic mistake.

With the help of her gang-including her best friend and expert hacker, March; and her ginormous, socially anxious pup, Genki-Kazu uncovers evidence that suggests the dognapping ring is bigger than she ever imagined. But the more she digs, the more dangerous her investigation becomes. The dognappers are getting bolder, and Genki could be next.
