Geography Club is a novel by Brent Hartinger. The story follows the main character, Russel Middlebrook, as he tries to come to terms with the fact that he is a gay teenager, while also trying to hide his sexuality from everyone else. When Russel discovers that one of the baseball stars and popular guys in school, Kevin Land, is also gay, Russel feels as if he finally has someone that he can be completely honest with. As Russel and Kevin start a romantic relationship, Russel also decides it is time to tell one of his best friends, Min, that he is gay. Min reveals that she is bisexual and has a lesbian girlfriend.

Russel, Min, Terese, Min's girlfriend, Ike, Min's friend, and Kevin all agree to meet at the local pizza parlor. Since they are all gay, lesbian, or bisexual, this group meeting allows the individuals to feel as if they belong somewhere for the first time. This leads them to form an official after-school club, the Geography Club, so that they continue to meet without anyone catching on that they are homosexual and bisexual.

While the pressure of being gay leads Russel down the path to stand up for and defend the rights of Brian Bund, the kid that everyone at school picks on, it also leads some of the other club members down a different path. Kevin continues to hide his sexuality, which ultimately breaks up his relationship with Russel. Min and Terese also separate because Terese wants to continue to hide who she is while Min wants to reach out and invite Brian to join their club, which could also put the identity of the group members at risk and exposed to the public.
