There is nothing more dangerous than magic...

Eleven-year-old Erskin is used to danger; she lives in the shadow of Mountainfell, a place of wild creatures and dangerous magic. When the most powerful and deadly creature of all – the fearsome cloud dragon – snatches Erskin’s sister away, Erskin must face her greatest fear and journey onto the mountain to bring her back. A terrible power is stirring, and it is up to Erskin to save both her family and her home.
