This document discusses different definitions of agency in young adult literature. It examines definitions from Oliver Wendell Holmes, Alice Mills, and Drew Campbell. Holmes defined agency as having both the capacity and responsibility to act independently. Mills' definition requires characters to consider options and make choices, but implies they must take action. Campbell argues characters have an obligation to change society, limiting their ability to not participate. The document concludes there is tension between individual agency and societal expectations for characters to create positive change.
