I love a great family saga! It was one of the things that endeared me so much to Life After Life and A God in Ruins. Some Luck focuses solely on the Langdon family and their extended relatives on each side. Each chapter deals with their lives on a yearly basis, beginning with 1920 and ending with 1953. 
 With the time span the author selected, we get to see not only the family grow, but also the major events happening in the world during those years. The characters are very well written and consistent. And though there are many family members, it was easy to keep everyone straight. 
 The book ended very abruptly, making it impossible not to move on to the next book. I enjoyed the book so much, that the only problem now is how quickly I can get a copy from the library!
