I should offer a little more about the Goldfinch. The story begins with a 13-year old boy whose mother is killed in a terrorist bombing at the Met Museum in NYC. He is there, too, survives, and, through a twist of fate that he isn't really to blame for, leaves the museum with the famous still life painting of a
goldfinch (by Fabritius). The story follows him through his grieving process, his changing living arrangements (as his guardianship arrangements develop over time), and later his adult work and connection to the antique and art communities. The painting connects him with his mother (it was her favorite painting in the exhibit they were there to see), but also generates hijinks as he struggles with what to do with a famous painting that has gone missing. It is an exploration of the gray areas of morality and why life is worth living even when circumstances break against you. In the end the author (Donna Tartt) takes some time to philosophize, not unlike Tolstoy in War and Peace, but speaking through the protagonist's voice, and much more succinctly that Tolstoy did.
The protagonist is a smart kid, wracked with guilt, and, after his mother dies, struggles to find adults whom he knows are in his corner. Hijinks ensue. Without getting too much into the details, I started empathizing with a kid in a tough spot, but almost immediately his decisions began to annoy me. The results of many of his own decisions, and many things beyond his control, put him in consecutively worse situations. Finally, he appears to have found an equilibrium, but the author uses time jumps to cover things up, then uses flashbacks to fill in some key information about what's been happening to our hero. He is clever and resourceful, but not especially interested in the morality of his decisions, but nevertheless remains hamstrung by his guilt. That leads to the philosophical exposition at the end.
Following the art world and antiques through New York, the story largely focuses on privileged areas of society and problems within them. The protagonist never really belongs in that world, except through his interest in art. Some of the discussions on the value of art/antiques and the marketplaces for them are pretty interesting. There are some interesting supporting characters, including his best high school friend who is a mad Russian (or Ukrainian?), and a woodworker who restores antiques. The story has a few surprising twists baked in.
As I'm writing this, I realize that I enjoyed the book, but I didn't love it. Critics did; it won the Pulitzer prize for fiction.
