Description: When Gerard signed the admissions paperwork for the Fordhaven School for Boys, he knew he was signing up for four years of sexual frustration. No one was gay at Fordhaven. Gerard was all-too-aware that he would be a virgin until he graduated. In his senior year, though, this stupid gay freshman disproves Fordhaven's straightness, and throws Gerard's entire world off-kilter.
