In a triumph for Mia's catering business and cooking school, Mia's Morsels is chosen to host a fall festival event in their Idaho mountain town--which means managing a bunch of stage moms and their social-media obsessed daughters as they get ready for the big beauty contest. There's a lot riding on the results of the Harvest Moon Festival--it's where the winning family receives an inside track to coven power.

But after one stage mom is found dead, and another winds up in the hospital, the coven suspects magical meddling. With a week to go before the coronation of the new queen, Mia must draw on her sleuthing powers to find out what's going on--and whether this competition has gotten a little too cutthroat . . .
