The Novelty Shop Nightmare by Cate Martin

Tabitha Greene grew up all alone, shuttled from magical academy to magical academy with no rhyme or reason. She never stayed in the same place for more than a matter of weeks. Ever.

That all changed when she moved in with her uncles to help them run the Weal & Woe Bookshop in the Square, a hidden magical neighborhood in Minneapolis. Now her uncles make her breakfast to start every day, her neighbors greet her whenever she passes them, and she has friends who mean the world to her, and she to them. She even found a brother she never knew she had.

All that, and a little dog too. What's not to love about that life?

But all of that is threatened when the father she's never met moves into the Square and opens a business of his own. The Shop of Wonders, where the proprietor knows just what item every customer never knew they always needed. People flock to shop in his store.

But when one customer turns up dead after leaving the store, Tabitha can't help suspecting the last man to see her alive. Even if implicates her father.

No, scratch that. Especially if it implicates her father.
