I was briefly tempted to put this down about 150 pages in. I knew I'd figured out 'the family secret' and did not want to wade through the rest of the story to have my hunch confirmed. Then by the end of the next few pages, the cat was out of the bag, and I realized the story isn't just about the secret being revealed. It's about what happens to the families involved when the truth comes out. I'm glad I kept reading - a great story by a great writer.
