Eilis Lacey is an Irish immigrant to Brooklyn after WWII. She takes a job as a bookkeeper and moves into a boarding house. While in America she sort of reinvents herself and finds romance and a career both of which seemed unattainable at home. But when a family tragedy takes her back to Ireland, she discovers what her life might have been like if she had stayed. And then she has to make a choice, go back to America where she has commitments and a life waiting for her. Or stay. I won't tell you the choice she makes and I'm not even sure it was the right choice.
I enjoyed this book and would recommend it if you enjoy historical fiction from this era. It has some romance, but I wouldn't catalog it as such.
