Freedom vs. Control

I believe this is freedom vs. control because people have the right to be free and not follow what others do. In this book i am glad Kayla is sticking up for what she wants and not following other people like her friend because she thinks it's the "cool" thing to do. People cannot control other people to get bar tattoos and all get imprinted the same. Seeing her dad die from the tattoo just means something is not right with this bar code tattoo, and Kayla has the freedom to find out and not get a tattoo like her parents, and best friend.
