The Lesbiana's Guide to Catholic School by Sonora Reyes

This was sort listed for the National Book Award YA award in 2022, and is just about what it says it is in the title--a chronicle of Yamilet, a young Mexican-American woman who along with her brother start at a mostly white Catholic school where neither of them quite fit in. They live with their mother, who doesn't know she has gay kids and their father lives in Mexico after having been deported. After being outed by her crush and ex-best friend before transferring, Yami has new priorities: Keep her brother out of trouble, make her mom proud, and most importantly, don’t fall in love. Granted, she’s never been great at any of those things, but that’s a problem for Future Yami. The thing is, it’s hard to fake being straight when Bo, the only openly queer girl at school, is so annoyingly perfect. And smart and talented. And cute. So you know how this goes, but the story is well told.
