Millie moved into her grandmother's old (and haunted) Victorian house shortly after her parents announced their divorce. That meant she had an entire summer to stay up late and play video games with her favorite person in the world, her Mimi. Millie didn't understand why Mimi would often leave in the middle of a raid and come back hours later bruised and bloody. Until one fateful night, Mimi came home with a mortal wound and confessed a family secret. Millie comes from a long line of curanderas and is charged with keeping the balance of the universe. Mimi assumed she'd train Millie when the time was right. Unfortunately, time for Mimi is short and the people of Sweet Bay have a supernatural predator on their hands. Millie has no choice but to take the reins.
