This line inside the class definition for "Book" that starts in the first column is an indentation error:

personal = Book("John Green", "Paper Towns")

It also doesn't seem to have anything to do with what the challenge has asked for!

Also, the last 4 lines that are outside of the definition don't seem to be related to what the challenge has asked for, either. Plus they contain "return" statements which are not allowed outside of a function or method.
