A middle grade graphic horror novel about two brothers who must uncover what terrors may be lurking in the depths of their local creek. There's nothing that Wade and his younger brother Andrew love more than fishing together. As summer is drawing to a close, they're excited for one last hoorah before they have to get back to school. But what starts as a typical fishing trip with friends Camilla and Tommy filled with homemade bait and friendly competition, quickly takes a darker turn. A heavy fog creeps over the creek and Andrew hooks something big--too big. In a moment of chaos, he's pulled overboard, and Wade must dive in after him. There, in the watery depths, the boys get a glimpse of what waits at the end of the line, and it seems far more monster than fish.
Could the recent storm have stirred up more than just water, unleashing something horrible from below? When the adults won't take their claims seriously, and Andrew starts to exhibit strange behavior, the brothers and their friends set out to attempt their biggest catch yet: evidence of a real-life monster living in their own backyard. But are they in way over their heads? As Andrew's condition worsens, only one thing is clear: they are in deep trouble.
