Emma Townsend, who sympathizes with the titular character in "Jane Eyre," finds herself lost in Jane's nineteenth-century world when a lightning storm catapults her right into Jane's body.

Sorcery is forbidden in the land of Oz, so for two years Zerie, Vashti, and Tabitha have practiced magic in secret, fearing that otherwise their talents will be taken away--but when they are finally exposed they discover that there are more dangerous secrets in Oz than they ever suspected.

Zerie has learned that the real threat to Oz is Glinda the "Good" and her alliance with the Nome King, and now Ozma has magically transformed her into a mermaid and asked her to infiltrate Glinda's underwater palace, and free the Glass Cat and her friend, Brink--and she still is not completely sure who she can trust.

Meri is puzzled and hurt because her former best friend has turned on her--but when she is given a magic mirror by her aunt she gets some help in sorting out the problem from Anne of Green Gables.
