The Book of Dreams (Chronicles of Faerie)

Fourth book of the Chronicles of Faerie. Dana, the half-faerie heroine of The Light-Bearer's Daughter, has been using her access to the land of Faerie to escape the troubles of being a teenager in a new town. But a dark, mysterious enemy is determined to sever the two worlds forever, thus dooming both. Just as the previous books explored Ireland's rich folkloric history, The Book of Dreams delves into the magical lore of Canada.
