I started a new book the other day, An Invisible Sign of My Own by Aimeee Bender. Its a first novel, though the sleeve notes indicate she has a collection of short stories. It’s a very interesting book. It’s dark but not really in the conventional sense. More slowly going mad than nasty or evil. I am enjoying it though. Her writing style; first person, disjointed, jumping from past to present, suits the story well. So far, I have to recommend it, but perhaps not if you are easily disturbed.
Update: Ive finished this now. The ending took some thought, but yes, recommended.
