I was assigned this book for my honors Biology class, and at first had some hope. We had read Animal, Vegetable, Miracle and it ended up being a drag, so when my teacher announced that we wered reading a book on gene therapy, a part of me was excited to read something vivid and interesting.
The book starts out with Corey's story, and up until about the 100 page mark, the book is wonderful. The only problem is, the book starts to get slow and monotonous. At certain parts, it feels as if you're reading a pictureless Biology textbook from the 60's that is mainly covering simple facts. Although the book moves on and becomes interesting again, it's a drag around the 100 page mark. Would recommend if you are interested in the topic, but I wouldn't recommend that teachers assign it, simply because of the inconsistency.
