Behind Her Eyes by Sarah Pinborough

 

This is a crap novel, really. Marginally competent crap on some levels--the prose isn't complete garbage, and the characters are reasonably well delineated (with the glaring fucking exception of the POV character who's lying about who they are the whole time)--but the basic story premises, especially like the core reveal, the supernatural shit bolted onto lucid dreaming, are pretty much shit. The characters are pretty universally detestable, which makes the early going difficult enough to get through that perhaps it should be a warning to just stop now. I kinda wish I had.
