Wayward Daughter by Alyssa Frace

17-year-old Genesis Belle would do anything to leave the monster hunting world behind–even make a deal with one of the world’s most accomplished hunters: her mother. All she has to do is kill the creature lurking in the shadows of their town before her mom does. If she wins, she can follow her cross-country road trip dreams without slaying monsters on the way, but if she loses, she’ll have to keep working at a hunting outpost masquerading as a dingy diner. She’s sure this bet is exactly what she needs to finally be able to do whatever she wants. Thanks to the help of the apothecary-in-training, Red, she assumes winning will be easy enough. He’ll help her with the boring part (researching monsters) and she’ll do the important part (killing monsters). It should be as easy as the pie she serves at the diner, but the further down the rabbit hole she goes, the higher the body count. And she’s pretty sure her mom’s shady monster hunting tactics are to blame. Armed with a broken mermaid artifact, that annoyingly nosy apothecary, and lots of spite, Genesis must traverse the monster hunting world and utilize her skills to win the bet and save the town from the magic lurking in the shadows.
