I like the science, future and ethics that must weave throughout this story. The concept of altering DNA has always fascinated me. Of course this comes with thoughts of what would you do if this science was available? I have parts of my DNA that would be nice to alter, but, at the same time, I'm not sure I'd change them since it's part of who I am. I'm not sure I would alter my kids' DNA to ensure they wouldn't have the same problem either, if given the option. Plus, I always love a good love story.
