Two of a kind

Lizzy and her two younger 8 year old siblings (twins), Hannah and Henry have never had an easy life. They had recently moved to their grandmothers old town, with their abusive father, who still hasn't gotten over the lost of their mother, who died a long time ago.

Lizzy loved where her grandmother lived. She use to tell her stories about the mansion that was on top of the gloomy hill in the town. About the man with scissors for hands that she fell in love with.

One day she explores towards the mansion and finds the hidden secret within it. Maybe grandma Kim's stories aren't just stories after all. And for once both Edward and Lizzy don't feel alone.
