Status Updates From NEVER TRUST A DEMON

I know that this is meant to be more of an elementary school book, or at least middle grade. But, it's grating on me. The protagonist is somewhat willing to consider the possibility she is seeing a ghost, is totally unwilling to talk about there being a demon, and all the demon has done so far is taunt her. It's a child's problem ("How do I steal/keep/give an amulet?"), with attention to a child's bedroom.
