Cary vs the Goblin King - Cary Redmond Short Stories, #9

Protectors don't get nights off. Girls' night means different things to different groups of friends. For Cary Redmond and her three closest friends, it means staying in and watching a classic 80s film while eating Mexican food and drinking margaritas. The perfect evening, with the perfect company. Until an unexpected guest crashes the party. Literally. In the ensuing wreckage, Cary discovers her night off has just become a work night.
Since she's a magical Protector, she's used to diving in to keep the good guys safe from the bad guys. But this time, it's her dearest friends in danger. And no one, not even the Goblin King, messes with Cary's friends.
