This story took a while for me to get into. Partly, it's that the protagonist isn't terribly likeable, and the main plot seems to be her just being horrible to people.

However, as things go on, you begin to enjoy getting to know her, and observing her interactions with people, her simultaneous intelligence and social cluelessness, it's hard not to start pulling for her. Even though you know very well that the crush she has on the musician (which drives a large part of the plot) is not going to turn out well.

It's a fascinating portrait of a person who has experienced deep trauma.

MILD SPOILER AHEAD

In the end, the emotional transformation is very satisfying, as is the ending, where she finally starts putting pieces together.
