Lily and the Prisoner of Magic

Lily and Georgie are trying to save their father. He is a magician and that was enough to imprison him, as magic is forbidden in the kingdom.  

But the girls cannot manage it alone, so they decide to ask for help from the famous sorceress Rose.  

To reach her, they must cross the ocean and face many surprises. 

Will Lily and Georgie have enough courage and ingenuity to deal with them?
