An ambitious teen girl is forced to continue her family's legacy of secretly impersonating the town's famous lake monster, but suddenly finds a real monster in the lake who wants to eat its way through the populace.

"Lemon Ziegler wants to escape rural Devil's Elbow, Pennsylvania to attend college--but that's impossible now that she's expected to impersonate the town's lake monster for the rest of her life. Her family has been secretly keeping the tradition of Old Lucy, the famed (and very fake) monster of Lake Lokakoma, alive for generations, all to keep the tourists coming. Without Lemon, the town dies, and she can't disappoint her grandparents...or tell her best friends about any of it. That includes Troy Ramirez, who has been covertly in love with Lemon for years, afraid to ruin their friendship by confessing his feelings. When a very real, and very hungry monster is discovered in the lake, secrets must fall by the wayside. Determined to stop the monster, Lemon and her best friends are the only thing standing between Devil's Elbow and a monster out for blood"--
