The Incredible Vanishing Book
It's not that you don't like it -- it's that you literally cannot remember anything about it from one minute to the next.
If you're interested in experiencing this unique reading phenomenon, try The Vanishers by Heidi Julavits. I would give you a brief plot outline, but I can't remember the plot. It has something to do with a woman who has powerful psychic abilities. There's a school for these people (like the school for mutants in X-Men?) and she has a mentor, and the mentor is trying to solve a mystery, and she gets involved in the mystery. There's a psychic attack, and an artist/pornographer, and a woman who may or may not be real, and a mother who committed suicide when our heroine was an infant.
There -- I actually surprised myself by remembering that much. I do remember that the plot is convoluted and confusing (one of my great writing teachers used to say, "There is no excuse for lack of clarity," and I think many authors need to learn that). Nothing feels real or authentic, the level of absurdity approaches comic book heights (maybe she was inspired by X-Men), and, worst authorial sin of all, it all gets boring. It's a soup with too many ingredients, and the ingredients themselves are often inedible.
The cover sure is pretty, though.
