Meg & Sue go to Wales to spend the summer with Gran Jenkins. They meet up with Gavin (Out of the Dark World), and run into strange events - places that come and go, a weird mist that swallows everything. Gran begins a legend that concerns an old castle that was once there and before long all three are swept up in it - for real.
