Their favorite campground is opening for winter break, so Cooper, Packrat, Roy, and Summer are excited for snowy fun while helping plan a winter festival. But when they see a lynx kit wearing a pet collar, watch a reckless snowmobiler dash across the ice, and are warned about a dangerous poacher, the young detectives and some cool new friends set off on their most exciting adventure yet. Can they solve the mystery and protect the camp's wildlife from poachers before it's too late? Award-winning author Tamra Wight returns with her fifth installment in the Cooper and Packrat series and this time she introduces readers to a whole new season of fun, more excitement than ever, and even a hint of young romance at the Wilder Family Campground.
