"But I'm tired of coming out. All I ever do is come out. I try not to change, but I keep changing, in all these tiny ways. I get a girlfriend. I have a beer. And every freaking time, I have to reintroduce myself to the universe all over again..."
All it takes is one little mistake. Simon forgot to log out of his gmail at the school library. This wasn't just some ordinary email account, it was the secret account that Simon uses to talk with Blue. Simon and Blue both go to the same school, they don't know each others' real identities, and they are both secretly gay.
Class clown Martin reads the emails and uses them to blackmail Simon. He wants Simon to help him get together with Simon's friend, new girl Abby. Simon isn't ready to come out, and he definitely doesn't want to expose Blue, so he makes a few lackluster attempts to help Martin. Abby isn't very receptive to Martin and she eventually starts to date mutual friend Nick. Their other friend, Leah, has secretly liked Nick for a long time, so it's very complicated.
Simon vs. the Homo Sapiens Agenda was such a good story. Simon is funny and awesome, and I liked reading his point of view. It feels like the teenagers are authentic, but not as scary as real teens. Becky Albertalli's book was so fantastic that I absolutely had to read her follow-up, The Upside of Unrequited, as soon as possible. Actually, that's my next review.
