"Fans of aspiring game warden Cooper Wilder and his friend Packrat—whose useful collection of miscellany resides in his jacket’s many pockets—will enjoy following the boys as their attention turns from setting up (with friends Roy and Summer) the premier winter festival at the Wilder family’s campground to learning about a probable fur poacher nearby. Part of the fun for readers is trying to outguess Cooper’s changing assessments as the clues pile up. Stylized, grayscale spot art is appropriately lighthearted and reassuring."—Kirkus Reviews
"An engaging mystery for wildlife lovers. Cooper and his best friends Packrat, Roy, and Summer are looking forward to a fun-filled week of outdoor adventures during the winter break in Maine. But after they spot a baby lynx in the woods and learn about reports of an illegal poacher in the area, the kids start investigating suspicious activities on their own. Facts about lynxes open each chapter, and animal-loving kids will appreciate all of the additional Maine wildlife details woven into this plot, not to mention the description of winter activities. A great choice for collections where mysteries are popular."—School Library Journal
"Wight not only creates engaging mysteries for young readers, she educates with background details of animals and nature, as well as woodcraft like camping, fishing and hiking"— Bill Bushnell, Kennebec Journal
