Kara Lin is Abby Abernathy's roomate at Eastern State University.
Very studeous. She is always doing her homework, and seems crabby most of the time.
Not much is known about Kara's outside relationships. She is often very stuffy but seems to care for Abby, often giving her unsolicited advice. She does not seem to like Travis, claiming he is co-dependent on Abby. Her and America seem to also dislike each other.
In the book Kara does a pretty good job of putting up with everyone around her. She seems to care about Abby as shown when she sends Finch after Abby when she rushes by looking upset. She is often annoyed whenever anyone bothers her in her dorm room and often leaves to shower whenever Abby has company.
"Do you know what co-dependency is, Abby? Your boyfriend is a prime example, which is creepy considering he went from having no respect for women at all to thinking he needs you to breathe."
