The Fairfield Frightless and the Children of the Lake - The Fairfield Frightless, #3

A summer vacation at a beautiful lakeside cabin sounds like a great way to relax. At least until a legend about an eldritch god of vengeance starts to become more than just a story. Anastasia Graves and her friends travel to the quaint tourist town of Bellshire nestled high in the mountains to celebrate their high school graduation. During dinner at an old inn they are told a legend of an ancient creature that sleeps within Bellshire Lake, one that feeds off anger and could spell the doom of the world if it were ever to reawaken.
At first, Anastasia appreciates it for the tall tale it is. But when strange things start happening around the cozy lake town, she starts to fear the story might be more than just something used to scare tourists. To complicate matters further, her attention is divided between two mischievous sirens who seem a little too interested in her, as well as a surly necromancer who watches her from afar. As the lake becomes more agitated and the bodies of missing townsfolk start to wander the streets at night, Anastasia steels herself to solve yet another mystery.
But when the truth of the legend finally comes to light, she realizes she might be up against something far more deadly than she ever imagined.
