The Bar Code Tattoo- futuristic genetics

This book is by Suzanne Weyn and I enjoyed looking at the science connections to genetics in it. It describes a future society in the United States that requires everyone to have a bar code tattooed on their inner wrist. Kayla, a high school junior, and some friends decide to refuse to get the tattoo and eventually figure out that it is a code for their DNA and genes. Therefore, the government can refuse services to people who may be doomed to cancer or another disease, and not even know it. It gets a little weird at the end, but also kept me interested.
I liked the piece that connected it to science and how sometimes the consequences of having knowledge, if used incorrectly, can be very scary. One of the best moments for me was when my students and I were having a discussion about genetics and I mentioned I was reading Bar Code Tattoo. One of my students who is difficult to connect with lit up as she made the connection to the book, what we were discussing, and me since she had read it too! That is always a neat thing.
