Walk on Water

Even though I didn't understand a lot of what was going on, I loved the first two-thirds of the book. I loved the stories about children who were sick and dying and needed heart surgery. I loved the stories about the doctors who worked on the children.

Then the story switched to a history of heart surgery in the world and I grew less interested. By the time I got back to the stories of the children, I found myself much less interested in what was going to happen.
