Clearly by looking at other books Clements wrote are for children or teens. However, myself not being a children nor a teen, reading his book, 'Things Not Seen' was definately not just another teen book from Clements.
At first, when I read about two or three chapters I thought this book will be about an avarage teenager looking for the real meaning of life and becoming more mature. (You know just another kid book thing) However, as I flipped through the book, there were more meanings to it.
Of course just like other stories about a teen, this book talks about an irresponsible teen growing up to be a mature young adult. Before the invisibility happened, Bobby's parents decided what is good for him or what he had to do. But after becoming invisible, soon he finds out that he is the one who needs to change and take in charge of his own life. By doing so, his problem (of being invisible) was solved and he bacame more responsible.
However, there are more important factors to look at.
Firstly, the bilndness comes out a lot in the book. The girl, who Bobby meets at the library, is a blind so when they met she did not know about Bobby's little secret and soon becomes his friend (or more than just a friend). She(the blind character) was the key to this story. If she wasn't a blind then it would've been almost impossible for Bobby to change and deal with his problems maturely. It was just because she was a blind, they became friends and grew up to be more mature while helping each other's problems. When the girl needed help, Bobby became her eyes, and when Bobby needed help, she became his body. This was quiet remarkable how the arthur thought about putting to completely unusual characters and made things work.
Moreover, when Bobby truned invisible, his parents did not know where to look at when talking to him. Bobby's mom wanted to touch and feel him to make sure he is there. During the whole time when Bobby was invisible, his parents needed his guide in order for them to know where he was (even Bobby describes how anxious his parents looked when they could not 'see' him.). The way that Bobby described about just observing his parents and how they reacted made it seemed like they are blind. By reading this part of the book, I could get a glimpes of how people with blindness might feel. Also, through the part where Bobby describes how other people act when they see the blind girl walking by herself (how people would not get close to her, and they glance at her but never stare) made me rethink about how the society thinks about people with disabilities.
Who decides what is normal and what is abnormal? This question kept popping out while I read this book. Of course not everyone becomes invisible or blind. But it could happen to people and there is no certainty that will not be me. A few years ago my mother was diagnose with breast cancer. I've never thought one of my parents will have such a thing. (and of course my mother didn't either.) But surely I realized that nothing is for certain. Anything could happen to anyone. (right?) Back to my point, who really decides people with 'visible' disability are abnormal? I can't even defind what really is being normal and what is not. Can anyone in the world say, 'I am a hundred percent normal'? by reading this book, we need to rethink about the definition of normality and abnormality.
Secondly, this book also contains another message; the way of looking at a life. Towards the end of the book, Bobby finds another person who become invisible like him about three years ago. That person (a woman) lived invisible for three years without even trying to find a way to get back to her life. She managed a way to not communicate with others in person and went out when necessary. Even when Bobby called her to tell her how to become visible again, she did not want to hear him and told him not to call anymore. By reading about her and knowing how she felt before 'the' incident made me understand about her situation. She probably felt meaningless about her life and when even she was not invisible she felt like the whole world is seeing right through her. Her situation with her parents were not satisfying although she always misses them. Also, I could assume that her self-confidence is at low. On the other side, Bobby (by becoming invisible) realized how much he missed being at school talking to his friends, (even he wasn't a very popular kid and had only few friends) playing instruments with others. He wanted so bad to have a regualr himself back, and when he did he couldn't be more happier about his life. Being in the same situation (in a very rare situation), Bobby and the woman had totally different perspective of view their problems. For Bobby not being able to be seen was a misery but to the woman it was a refuge. Not being able to be seen by others made her feel more comfortable and feel sheltered from her reality (living with her what-she-thought miserable life). This part was surely unexpecting and I was surprised, because there are alot of times that I thought some people's life was simply easier and better than mine since they were born with a lot more things than myself. But even two people are given the same exact thing, the result could come out very differently. If one is sucessful than others, it is not because he/she was born with more things but because that person looked at the situation differently and made a crisis into an opportunity. This book tells this lesson very clearly.
In conclusion, this was not just another teen fiction from Clements but it had deeper thoughts and messages that could make its readers rethink about ourselves.
