Under the Hat - Sara Bourgeois

Blythe Fairfield chose to stay in Cauldron Hollow. She's not sure the town has chosen her back.

Her relationship with Sheriff Paine Wilder is in ruins. Her bank account is worse. The only job she can find is running a cash register at the local grocery store, where her boss is a conspiracy theorist, her customers include a woman who screams about paying for eggs, and the one friend who made it all bearable keeps talking her into things she shouldn't do.

Then a reclusive prepper turns up dead on his rural property, and Blythe finds more than a body. Buried beneath the man's unfinished root cellar is a book of spells that should not exist, magic that breaks every rule Blythe has been taught to follow. She can't leave it for the police. She can't destroy it. And she definitely can't stop thinking about what's inside.

Someone killed a man for this book. And Blythe just brought it home.
