You may have squashed it into fewer models, but the relationships do not map the real world relationships intuitively. You have that a Book has many Roles, whereas in the real world a book does not have roles at all, it is the author that has the roles in association with a particular book. Also by using a string for the role_type you will have many Role records with "MAIN_AUTHOR" for example. If you later decided that "Primary Author" would be better you would have to change the string in many records.
