Kassy O'Roarke, Geocacher: Pet Detective Mysteries Book Three

Just days before her thirteenth birthday, Kassy’s only wish is to escape from the cramped tent she shares with her brother and his farting ferret, her not-quite stepsister and her squirmin’ vermin puppy . . . and a miniature goat with an appetite for underwear.

Kiki the koala needs to get to the National Zoo in Washington, and the gang is on the world’s most fun road trip to get her there. On the way, they camp in the Shenandoah National Forest, where they enter a geocaching contest full of riddles and puzzles to test even the brainiest middle graders. 

Determined to win the contest—and a brand-new tent—Kassy faces off with the cheating Cheevers and risks losing Kiki for good. Can the gang outsmart the Cheevers, win the contest, and still get Kiki to her new home at the zoo?

Join Kassy's fun-filled middle-grade adventure cracking riddles, detecting clues, and solving a whole zoo of animal trouble in the third book in the Pet Detective Mysteries.
