Ethan, Devin, and Gianna are Pokemon trainers, and with the help of their favorite Pokemon and the Team Mystic gym leader, Carlo, they're ready to take on both the real world and the video game world in Pokemon GO! But when someone breaks into the local doughnut shop and steals a valuable batch of doughnuts, it looks like the shop might close--taking Team Mystic's only gym down with it! The friends are determined to crack the case, especially when their first clue, found in Devin's Pokedex, seems to point to a Team Valor plot? Can Team Mystic band together to track down the thief--and defend their gym?
