In this 5th book of the spell sister series where Gwen and Flora have another exciting adventure to try and rescue Grace, the spell sister who has power over the seas. Gwen got to visit her family and I liked her little sister who wanted to be just like Gwen. I did not know that children had to stay away from their parents in the old days.
