It's Not The Great Pumpkin, Maxie Duncan (Maxie Duncan #1.5)

Maxie Duncan wants to celebrate her first Halloween as a witch in style. Unfortunately for her, the Supernaturals don’t celebrate it like humans do. They would rather sit at home, watch movies, and hide from the spectacle the norms think creatures of the night are.

She needs help. She needs to fine a way to restore the joy Halloween use to bring. She comes up with a plan. Throw the biggest party Enchantment Cove has ever seen. Can the Supernaturals that live there be convinced there is fun to be had in even the most backwards of traditions?

Maxie has her hands full with the plan, but if anyone can pull it off, it’s her. Too bad something is dead set on crashing her party of the year. Now the night may really be “to die for.”
