Query: Amazing!

I've always been a fan of Rachel Roberts's AvALon: Web of Magic books. Song of the Unicorns is the first book in a new AvALon series called Quest for Magic.Emily is going to visit her father and step-mother with her two best friends, Adriana and Kara. Emily doesn't like the fact that her father's new wife is trying to make friends with her.But Emily has hardly enough time to think about that when she finds a cave while horseback riding one day. She and her friends discover something amazing inside the cave. Tons of baby unicorns from the mythical world of Aldenmor.The unicorns were sent to Earth by mistake and now they must be sent back to their own world before they grown too much...and before someone discovers a buch of rainbow-colored foals in the girls' cabin.I give this book two thumbs way up and am looking forward to the next book, All's Fairy in Love and War.
