For months I have been looking for a story, it starts with a man who has an ability to use his mind in a supernatural manner.

Later we see him helping out some older ladies when their car broke down. In turn he becomes friends with the family.

In turn he starts going out with the daughter who unbenknown to him is a witch. She in turn gives him an opportunity to experience what it is like to be a girl through a temporary body swap.

She swaps back but he remains a girl. As a result he becomes a witch like the daughter and the family are not happy as they believe the new witch is problem.

Later in the story we see the new witch escape from a warded and locked room using an unknown power. She is recaptured and a warlock is chosen to guard her room so she does not escape while her future is decided.

Eventually she and the daughter escape to try and find a place where they can not be found. Yet they are still found through witch tracking by members of the coven.

It has been bugging me that I have not been able to find this story or remember where it was posted. If anyone can suggest where to look I would be most grateful.
