A Taste for Red: 08/01/16
In A Taste for Red by Lewis Harris, Stephanie Grimm, who prefers the name Svetlana, believes she is a vampire. She prefers to sleep under her bed, doesn't like the way certain people smell (like her teacher), and prefers red foods above all others.
She's also having to deal with a huge upset in her life, going from living in Texas and being homeschooled, to living in California and attending middle school.
Svetlana with her taste for red things reminds me of Marceline from Adventure Time. Her neighbor and confidant, though, is more like either Miss Spink or Miss Forcible from Coraline by Neil Gaiman.
Svetlana's growing abilities lead her to uncover the true evil that has befallen her new town. It's a great middle grade mystery with horror undertones. It would also recommend it to fans of fantasies like Buffy the Vampire Slayer.
