I think out of all my characters, Jenny has the most emotionally demanding role. Eileen can and will happily continue to blast villains away. Jenny has to accept her mother did that for a living and still sometimes keeps her hand in to help her old world out. (This is particularly true when in my second novel, The Cherry Tree, Eileen is trying to put the Queen back on her throne). And it is not going to be a case of suddenly accepting that magic will be a major part of Jenny's life (she has no real choice over this as Eileen and the Queen know. Once magic makes its presence felt in someone, it doesn't go back in the metaphorical genie's bottle).
Jenny is going to spend years adjusting to her new reality. Accepting your mother is a fairy godmother is one thing but it is not the kind of news you want to broadcast unless you want your sanity questioned. So Jenny is going to have to find ways of covering up her mother's past and ensure both husband, Paul, and father, Derek, continue to remain ignorant of what's going on here.
Out of all my characters, Jenny is the one I feel most sorry for!
