The Trevi of Torvain (Kingdoms of Kailar)

Liana is the young leader of the Trevi, the tribes of magic users who live in the Erean Forest. They live in peace and avoid all contact with the Humans who live outside their borders. However, when the kingdom to the north threatens to annihilate them, Liana does the unthinkable: she turns to the Humans for help. In her quest to save her people, she meets many new friends, discovers abilities she never knew she possessed and changes the future of the Trevi forever.
