I really enjoyed Hourglass by Dani Shapiro. Check out my review on KQED. Excerpt:
My 15th wedding anniversary is in June. It seems impossible that my husband and I have been together for that long. The first 10 years of our marriage galloped by, or so it seems to me, before we finally had a child. Now my son is turning 5, my parents are elderly, and I’ve been married 15 years. These facts don’t feel real to me, but I guess they are anyway.
