This book is quirky.
The concept of describing what it's like to learn to see for the very first time was fascinating, and I loved the situations this brought up.
The characters are so flawed and scared, they repeatedly make rash decisions that ultimately hurt everyone, especially themselves. I wouldn't say that this is an optimistic book on the topic of relationships, but I said say it's honest.
Not a book I would reread, but it's enjoyable.
