The Crone's Stone

As the last Keeper of the vile Crone's Stone, 17 year-old Winsome Light has inherited a terrible legacy - for Satan's mistress does not take kindly to thieves. She wants her powerful stone back and the only one left to hide it is Winnie. The problem is: no one told her!
The Crone is coming to take back what's hers and Winnie had better be ready... This is no fairy tale.
