The Sisters Four

They are all sisters living in a castle as princesses under the queen- their mother- Queen Terra Rose.
This is a very bad description. LOL. This is my first book and yah.
When they were young, their castle was invaded and they were forced to flee. Their mother hid them at the four corners of Hathor- their planet. There was a prophecy that predicted that they would all reunite when the girls became of age. Fast forward to their fourteenth birthdays. They reunite and set out on finding more about who they are which leads them to the ruins of their castle. They find a tapestry of them as babies and their mother. They slowly put pieces together, find their mother and restore the castle.
