Linguistic diversity is integral to the cultural diversity that ensures some humans will survive in the event of one of the periodic global catastrophes. Local indigenous languages hold the keys to to survival because they contain the nouns, the names of the plants, insects, birds and mammals important locally to human survival.
Nearly all human cultures plant gardens, and the garden itself has ancient religious connections. For a long time, I've been interested in pre-Christian European beliefs, and the pagan devotions to sacred groves of trees and sacred springs. My German translator gave me a fascinating book on the archaeology of Old Europe, and in it I discovered ancient artifacts that showed that the Old European cultures once revered snakes, just as we Pueblo Indian people still do. So I decided to take all these elements - orchids, gladiolus, ancient gardens, Victorian gardens, Native American gardens, Old European figures of Snake-bird Goddesses - and write a novel about two young sisters at the turn of the century.
