From the description:
"What might have been an ordinary fishing trip becomes an unforgettable adventure when twelve-year-old Sawyer Brown pursues a legendary giant catfish and a stolen ring that may hold the key to his mother’s life.
Sawyer’s family runs a catfish farm in rural Mississippi. When his widowed mom gets sick after a pond “cat” swallows her wedding ring, Sawyer is sure the missing ring is to blame. Strange clues and a local myth convince him that the pond cat has become a meal for a far more challenging catch. He sets out with two friends and his stowaway little sister to solve the secret of the ring.
Journeying deep into a remote bayou, the foursome must rely on their wits and each other to navigate the teeming swamp, outsmart a sneaky poacher, and overcome their differences in pursuit of a colossal catfish. But this is no ordinary fish. This is Ol’ One Eye—the biggest, oldest, smartest, and meanest darn cat that ever swam the Yazoo River!"
