Karen Joy Fowler's "We Are All Completely Beside Ourselves"
I challenged myself to read thirty books, and find it funny that the only one I at some points actively disliked was my final one.
Some elements of my distaste may have been Fowler's intent: I disliked the narrator's mostly simplistic, sometimes patronizing, tone, and was often annoyed at her misrepresentations and falsehoods when it came to explaining Psychological viewpoints, and at one point, Chinese characters.
But I don't want to be too negative, and my experience with this novel may have been ruined by a spoiler I encountered before beginning it --- DON'T read other reviews if you'd like to read this.
The concept of starting stories in the middle was completely charming.
