This book was fine. My issue with it was I felt it was predictable, and some of the plot points that were meant to be surprises were easy to see coming based on a combination of "well there's 10 pages left in this book, only one ending could really happen in 10 pages" and the narrator wondering a lot but juuust missing the right answer.

The daughter had basically no characterization. She might as well have been a life size doll. Then again, the spouses didn't have a ton of characterization either. I wanted more from a book that sets out to closely examine a relationship.
