Prepare to have your mind blown! There are not one, but THREE in The Goldfinch: Boris, Hobie, and Pippa. (Actually, I've seen mixed reactions to Pippa, but I liked her.)

Also Theo's mom, and the doormen on Theo's old building, and... actually I even liked Theo, but in a much more conflicted way than I liked most of the aforementioned characters, it was definitely a liking mixed with "Theo I KNOW you are a trainwreck but there are some thing that does NOT excuse."

Also there is an adorable dog.
