Juliet Marillier said this quote
“ The man journeyed far, and he heard and saw many strange things on his travels. He learned that - that the friend and the enemy are but two faces of the same self. That the path one believes chosen long since, constant and unchangeable, straight and wide, can alter in an instant. Can branch, and twist and lead the traveler to places far beyond his wildest imaginings. That there are mysteries beyond the mind of mortal man, and that to deny their existence is to spend a life of half-consciousness. ”
