Of course Avery Marsh's parents decide to divorce her senior year of high school, but what's way worse, they're shipping Avery across the country to spend the year with her extremely closeted, absentee half-brother Lucas and his secret boyfriend. And it's great that Lucas is living his truth or whatever, but he couldn't have told his bisexual, nonbinary sibling earlier?

Now Avery has to spend their last year of school in Middle-of-Nowhere, Virginia, navigating new classes, explaining their pronouns to the cute boy in math class, and making new friends.

Told in journal entries, ALL I KNOW SO FAR is a queer coming of age story about love, hope, and resilience.
