Read if you MUST finish the trilogy
The pace of this book is slow, like the first two. The addition of the male narrator helped me recognize whose perspective I'm listening to, though his female voice is ridiculous. It was nice to hear things from Four's perspective. I guess this was done for a few reasons, including the fact that there's another book outside the trilogy told from Four's perspective, and this was a setup for that. The plot was very linear. These books are like a character study of damaged people, without judgement. And the exploration of why people make choices and how those choices impact your life and those around you. More plot development or longer books would have helped this story.
