The Witch on Exchange

Survival rules in the town of Kenterfield: Never get in the way of the Light Witch if, before she receives permission to perform magical activities, there’s only one step left for her—finish three months of service with the town guard!
Never get in the way of the Dark Witchlet if there are only three months left before her investigator’s working contract expires!
And God forbid they get in each other’s way! Then all ill-wishers and troublemakers will have to save themselves by running. To some unknown power that “drinks” the magic of magical creatures, it’s recommended to bury itself in the nearest cemetery, while the townspeople will simply have to hide—because there’s nothing scarier than these two in the same territory.
Though no. There is. A nasty witch and a witch in love.
