Mystic Miracles - Book 1 - C. A. Baxter - Bog

Imagine a world, not unlike the wizard's world of J. K. Rowling, but a mystical world, set in the angelic realms made of 10 kingdoms where even angels have their problems and go to school! The Head Angel at the Angel Academy calls upon the talents of the crystal child - Crystalina - who has a special gift for working with crystals and along with the Crystal Council, she uses her powers to protect and save the 10 kingdoms from enemies, one such enemy being the evil Sharaha, the Black Crystal Queen. Crystalina needs help from her brave band of friends, Luke and John (two angels in­ training from the Angel Academy who have to earn their wings), one knight to be, Jeffrey, a girl called Angela and Gravitas, the King of Gravity and Pelippa, the Queen of Speed.
But will that be enough to defeat Sharaha, the ruler of the Kingdom of Sound? She schemes to cause havoc in the Kingdom of Light and on Tempura, spreading disorder throughout the other kingdoms. She hopes that by doing so she can overthrow the Crystal Council in the process. Will they have to call upon higher help from that mightiest of mystical creatures - the King of the Unicorns?
