I really loved The Namesake. Her other books are short story collections and her themes are so consistent that the collections start to feel a little samey after a while, even though the stories are individually always fully transporting.

All her writing is quiet and domestic and sort of upper class, but rooted in these internally-epic identity struggles. She's got a really nice writing style where even though no particular words ever leapt out as "poetic", the narrative itself led so gently and inexorably forwards that I found myself really affected.
