10. Ready Player One by Ernest Cline
9. The Hate U Give by Angie Thomas
8. The Interestings by Meg Wolitzer
7. A Little Life by Hanya Yanagihara
6. Kitchens of the Great Midwest by J. Ryan Stradal
5. Where'd You Go, Bernadette? by Maria Semple
4. We Are All Completely Beside Ourselves by Karen Joy Folwer
3. Prairie Fires: The American Dream of Laura Ingalls Wilder by Caroline Fraser
2. The Great Believers by Rebecca Makkai
1. The Animators by Kayla Rae Whitaker
This list is probably missing Olive, Again, but what should it replace? Also Night Film. And probably Everybody's Fool. Discretion is hard. (This could be my motto).
