All of the Anne Tyler books I have read have had some depressing undercurrents, but the quirky characters and humorous writing keeps those books relatively lighthearted, despite heavy/sad themes. This book, however, is just sad. It still has quirky characters and an interesting plot, but the humor is not really there (and is not trying to be there). It's a very realistic look at the way couples can fundamentally disagree and clash, and it's told in an honest and real way.

I would recommend it, but not if you're feeling blue or in a troubled relationship!
