I thought SCAN was an excellent book. It was very adventurous with descriptive wording. I thought it was clever the way the authors made it seem so real. I also really liked that they left it open for a second book. The one thing I disliked about it is that it had a ton of bad words. My favorite character was Tate because he is so smart about almost everything and he tries his best at everything he does. I am going to give this book five out of five stars, but hopefully with the next book there won’t be so many bad words. I would recommend this book to ages twelve and up because there are lots of bad words, some death, and other mature content.
