For Corbett Griffith III, divorce and two busy parents mean goodbye city life, hello great outdoors. With their busy Chicago careers and schedules, his parents just don't seem to have any time for him. When his mother sends him to his uncle's Wisconsin fishing resort for the summer, Corbett feels that there's no one pulling for him or caring what happens to him. But all of that changes at Whispering Pines Lodge, Corbett learns he is never really alone, thanks to his Uncle Dell, who takes care of him, and his new friend Pike, who pulls him into one mischievous adventure after another. It's a summer of change for ten-year-old Corbett-even his name changes, when a cute girl calls him "Griffy," a nickname he likes enough to keep. Griffy and Pike spend the summer searching for adventures and cool things to do. When Griffy catches two elusive walleyes, he is surprised to discover how much he likes fishing. Eager to test his newfound skills, he and Pike are stunned to hear that a seventy-pound muskie is on the loose. They resolve to catch the ferocious fish, no matter what. For Pike catching a world record muskie would be about the sport. For Griffy it would be about something more. Maybe, just maybe, if he caught that fish is parents would take notice. Think alligator. Think prehistoric beast. Think mean. Will they be able to catch the muskie and stop it from attacking anyone or anything?
