Confusing

"I realise this is a children's story so perhaps I am expecting too much but I found it to be very confusing. It isn't clear who the main character is besides a name and a place she lives... or does she? Is she a ghost or is she real. The POV goes from third person to first person- quite a leap. The other girl in the story comes out of no where and it almost feels like she is imaginary. The is no sense of reality here at all. The characters are vapor-like, having little personality. This feels like a ghost story but that isn't clear. There are hints in the summary of this young girl saving something or someone but that doesn't seem to really play out. Maybe if the plot were stronger, the characters more fleshed out. Having some significant action, scenes that show who the characters are and what the story is about would be helpful. It leaves more questions than anwers which is fine for a beginning, but nothing seems resolved. Keep writing."
