The main audiobook narrator (there was a second one for only a few minutes and he was fine) sounded like a female robot. She probably lowered my enjoyment of this book. The story was good, but I disliked adult Sadie. I liked her as a child, and as a college student, but then I disliked her as an adult. She was one of the most unpleasant characters I have ever spent time with in a book. By the time she virtually abandoned her company, I was not surprised. I knew she was going to leave everyone and act like a bitch. It got tiresome. I get that a lot of the tension of the plot was propelled by her needless drama, but I felt we didn't need it. I really like Sam and Marx, their friendship, Sam's struggles with his handicap. 3.5 stars.
