Free Food for Millionaires by Min Jin Lee

The "Free Food" mentioned in the title is made available for traders and executives in an investment firm. As a homeless and semi-starved Korean American, our heroine looked upon the bounty provided at her new job with a sense of irony. Casey was spending her twenties trying to find what she wanted to do in life. She'd graduated from a prestigious college and was thrown out of her parents' home for not displaying enough obeisance to her father. Thus the period of homelessness and hunger followed by a period of comfortable employment. Her relations with her friends, lovers, and family form the nub of this well-written and compelling novel.
