This book makes me feel curious for how he first started to be invisible. The book is unique becuase it has lots of mysteries and it has science fiction to make it exciting. This book is different because it's about a person's life and its mysteries. My favorite characters are Bobby and Elise because they are curious kids and they find lots of information that others can't. They remind me of myself because I am also curious.
I recommend this book to people who are interested in science fiction and mysteries. Students in fourth and fifth grade would really like this book.
