City kid Corbett "Griffy" Griffith III can't wait for summer vacation to begin. The twelve-year-old's annual trip to his uncle's Wisconsin fishing resort promises more than adventure and mischief this time around. It offers Griffy a much-needed break from his mom's new boyfriend in Chicago and much-needed time with his busy dad up at Whispering Pines Lodge. Determined to impress his absentee father, Griffy enlists the help of Pike, his best friend at Whispering Pines, to master everything about boating and fishing. He'll brave the smelly, torture chamber-like fish house. He'll battle the vibrating motor on the Lucky 13. Griffy will do whatever it takes to get his father's attention. Even a knife injury and a near capsize won't keep him from completing his goal. When a vicious snakehead fish is caught in the waters of Lost Land Lake, the summer takes a sudden and disastrous turn. Strange events lead Griffy to one disappointment after another. He and Pike must unravel a mystery that pits them against a trusted friend and an invasive species fierce enough to ruin the lake and the livelihood of everyone on it. Can Pike and Griffy save Lost Land Lake before it's too late?
