Simon vs. the Homo Sapiens Agenda by Becky Albertalli
Simon is falling in love with someone he’s never met, and maybe never will. He’s been emailing with “Blue” anonymously ever since finding his Tumblr post. But their anonymity is threatened when Martin accidentally logs in to Simon’s email. Now Simon is being blackmailed into setting Martin up with his friend Abby or risk being outed to the world. And worse, possibly losing Blue in the process.
This story is beautifully written, focusing not only on Simon’s budding romance, but also on his relationships with friends and family and the effect coming out has on everyone in his life. Recommended for high school and up.
