As a weird, kind of surreal fantasy story, I'm enjoying this. Although there seems to be a number of plot holes.
The queen can't tell anyone about her condition, but the hatter ought to be able to tell someone. Does no one else know about the mind controlling abilities of this rival nation? How do they not have any defense against the dark arts/have not been taken over ages ago? If the control only works at short range, why is she not taking a trip far away?
