The Magical Cheese Emporium by Sarah Beth Durst (The Spellshop Book Four)

The World Burned. The Library Fell. Now, the Magic is Ripening.

When Eloren joined the revolution against the empire, she didn’t expect to lose everything ― her job, her purpose, and her closest friend. After the Great Library burned down, she had no other choice but to return to the only home that will have her: her grandmother’s shop.

Now, Eloren is stuck at the Magical Cheese Emporium in the remote island of Dew. But the unicorns won’t come near her, there’s a monster in the cheese caves, and Eloren is more into books than cheese. The only good thing about coming home is reuniting with Garyn, her childhood friend and clever inventor.

When Dew’s governor imposes impossible taxes on small business owners like her grandmother, Eloren knows one thing: she didn’t take down the emperor just so someone else could exploit good people. And in trying to save her community, Eloren might finally agree to call it home.
