The Drowning Girl is by far the most literary work I have read this year. It's too bad this sort of thing doesn't make more of an impression on me. I find it hard to be truly fair to dark fiction, but it's out there as a major element of speculative fiction so I do keep trying.
This is a story of madness. Not over the top pathology like Hannibal Lecter, but a more ordinary sort of madness that millions have lived with. India Morgan Phelps, or Imp, sort of controls the madness with drugs and therapy, but her ghost story is waiting to be told. Writing is her attempt to sort out madness from reality, and if there is any good news here it is that she succeeds. And as I said, it is literary--very stylistically complete, everything about it intentional, fully developed backstory. And even though I do not care for this genre much, I found it grew on me at the very end. So I would say that if you liked The Red Tree you will definitely like this one, though you have probably already bought it. Three stars from me, for the ending. I value endings, more than some do.
