Gwen is a young girl...a very special young girl. Unbeknownst to her, but known to the Council of Cats, is that Gwen is a witch, and will come into her powers soon. She needs someone to teach her about her abilities, and The Council decides that someone will be Rosetta. Rosetta is sent to Gwen's home, where luckily, Gwen's mother allows her to remain. Soon, Rosetta reveals to Gwen her mystical powers, but now Rosetta's task has grown more complicated: To teach Gwen more, Rosetta has to interact more with Gwen, but Gwen's dog Inky doesn't like her one bit, and Gwen doesn't believe she can use magic without Rosetta. What's a cat to do?
