What's the Name of That Book??? discussion

there was this book about a girl who's mom is a teacher at her school, so she has access to the school until the late evenings, even when everyone left. she had a blog where she wrote letters for money, and she had feelings for her best friend. i'm pretty sure her best friend was a girl, and some guy ends up finding about it? he's rich and he's new and they somehow go to a carnival together?? this book was published within the last 10 years and it's a lighthearted, coming of age book, and young adult, but i just can't seem to remember exactly what it was called.

What is wlw? Please use whole words rather than acronyms. Many people don't understand acronyms.

I think it's supposed to stand for women-who-love-women, but it's definitely a newer acronym.

I'm more old-school, lol. Lesbian and bisexual are not bad words!
