My 7-year-old daughter has discovered, and become enamored by, a series of novels called Warriors. The observations of animal behavior, human archetypes, and themes of integrating opposites have caught my interest, too. A definite improvement over fairies and princesses.
“Warriors … follows the adventures of four Clans of wild cats in their forest homes…. The New Forest in southern England was the base for the forest where the original series took place. Other influential locations include Loch Lomond, the Scottish Highlands and the Forest of Dean.
“Authors that Tolkien, Ursula K. Le Guin, Shakespeare, J. K. Rowling, and Enid Blyton. Major themes in the series include forbidden love, nature versus nurture, the reactions of different faiths meeting each other, and characters being a mix of good and bad.”
