Dark Spell

15-year-old Callie Hall has just found out she's a witch, and things keep going wrong. Sometimes her mind seems to make things happen, things she can't control. She can set fire to things without a match, and when she's angry people can get hurt. Her friend Josh understands she's a bit weird, but its only on a dark and dangerous visit to the tunnels under the ruins of St Andrews' castle that he realises just how strange she really is. Something comes back with Callie -- in Callie -- something she can't escape. Can Callie control her power long enough to send back the darkness, before it.
