This is one of those Teen books dealing with mental illness, except with a paranormal twist. It’s difficult to describe, there are these murmurs and then wraiths or something in mirrors and they want to put their life essence into people and take them over…I didn’t really get into that stuff in my review, which you can see here. It’s basically about a girl who just experienced the loss of her sister and now is worried that she may be going crazy as well.
