Digging to America by Anne Tyler

Rarely do I finish a book and feel like tossing it across the room. It felt so completely plot-less to me. It ended and I was left with a "so what?" feeling. I wasn't a fan. I kept reading it because I related to Maryam, an expat in a foreign country. I began to wonder if I will always feel like she does, not American but no longer considering Iran home either. I see there are lots of discussion questions on the web about this book and maybe if I took the time to answer them I might get more out of the experience but I just didn't relate enough to any of the characters to care about their lives.
