The Unlikely Hero of Room 13B, is not one of my favorite books. Nonetheless, Teresa Toten is a very skilled writer. She is able to show every emotion there is to finding love and losing it.
I think that teenagers who are religious and believe religion helps solve problems would prefer this book over teenagers who are not religious.
Most of the characters were very well developed. Toten pointed out many behaviors that those dealing with OCD might have when they feel different emotions. For example, when Adam was nervous or scared he would tap or count in his head.
