Pros:* It's not dystopian (but still awesome)* Genetics* San FranciscoCons:* Characters are a bit one dimensional* Science is minimally explainedI love YA, in fact it is the majority of what I read. However, this is a book I really wish had been written for an adult audience. I kept thinking back to my middle school years when I tore through all of the Michael Crichton novels. I just remember dense pages of scientific explanation. I wish this book had that. Not that it's bad. It's a good read (I knocked it out in about 2.5 hours) and I really enjoyed it. I just wanted a bit more.
