Two brothers and their wives share a 2 family house in Brooklyn. Rose and Mort have 3 daughters, while Helen and Abe have 4 sons; Mort longs for a son. Rose and Helen, who are extremely close, deliver their 4th and 5th babies on the same day, during the Great Blizzard of 1947. Rose has post-partum depression, so Helen steps in to help her and her family. Rose ends up resenting Helen, and refuses to spend time with her. The story goes through 23 years of life from the perspectives of Rose, Helen, Mort, Abe, and, later, that of 2 of the daughters. We see the differing impact various decisions and occurrences have on each of them. I highly recommend this book if you like character-driven stories.
