Star Split by Kathryn Lasky

Star Split by Kathryn Lasky is set in the year 3038. Scientists have figured out how to rid embryos of disease and even how to select certain traits for them! The Genhants, or genetically enhanced humans, carry an extra chromosome which makes this possible. The Originals, while still free of debilitating diseases have not been able - usually due to lack of money - to select certain traits for their children. Every year a special ceremony is held where new Laureates are announced. These are people who have made such great contributions to society that their DNA is collected so that clones, or ambullae, are created from them. Ambellation is strictly prohibited under all circumstances and is punishable by death - both the parents, the original child and the clone are incinerated. So, what happens to Darci, a typical Genhant teen, when she goes to rock climbing camp and comes face to face with her identical ambulla? Suddenly Darci's and Vivian's worlds turn upside down as they learn about a secret, underground movement to change the way their society operates.

This was a really interesting book. I can see how our society could get to a place like this, and I can see how easily genetic selection could get out of hand. This book reminds me a little bit of The Adoration of Jenna Fox by Mary E. Pearson and of Double Identity by Margaret Peterson Haddix. I like this type of science "what if" story.
