This is truly a spectacular book! It's well written and the research for it it spot on. The characters could have been the kids from my neighborhood. I find it very easy to get wrapped up in this book. It's not only for teens but adults too. I hadn't heard of some of the things discussed in this book. It is a bit technical in spots but I doubt any teen or adult will have much trouble with it. This should be part of your teens library! I believe Dr. Schewe struck gold here!
I didn't find any issues.
I gave this one 5 cheers out of 5 because it has all the things teens like. You'll see, they will love it.
