The Goldfinch by Donna Tartt

Aged 13, Theo Decker, son of a devoted mother and a reckless, largely absent father, survives an accident that otherwise tears his life apart. Alone and rudderless in New York, he is taken in by the family of a wealthy friend. He is tormented by an unbearable longing for his mother, and down the years clings to one thing that reminds him of her: a small, strangely captivating painting that ultimately draws him into the criminal underworld. As he grows up, Theo learns to glide between the drawing rooms of the rich and the dusty antiques store where he works. He is alienated and in love and his talisman, the painting, places him at the centre of a narrowing, ever more dangerous circle.
