A Purple Sky is an epic poem written in couplet rhymes and metre, narrated by Zephyrus, a living disc-like spacecraft. The story begins with three young people, Bob, Ishpa, and Sal, who head into the wilderness in search of an old reclusive native man, Makwa, who Ishpa had met by chance, or was it? There appears to be more going on than they realize, when in late winter close to starvation, they find strange footprints in a fresh blanket of snow near their wilderness cabin. These footprints vanish but lead them to some moose, one of which they must kill to save themselves. As it turns out they find the old man and learn of a dark secret he has held to his chest all his life. This secret is eventually revealed as they befriend a strange beautiful woman, Raven (Pana), who claims to be his mother and an alien who for millennia resided on earth and in Zephyrus, who is as well a soul-bank for Raven's dear departed friends and lovers. Once adjusted to this surreal reality, they embark on a journey that takes them into the heart of humanity and beyond to her dying planet, Xaras, to meet the phantasmagoric Crow (Pax), her brother of sorts, and last of their kind. Ultimately, Raven must make a choice about her legacy and what it means in the history of civilization.
