"What a master storyteller! I've read my share of post-apocalyptic screeds (i.e. James Howard Kunstler's works), and this is the best ever. The idea is amazing-a microbe that solidifies the world's oil. His venturing into the metaphysical is never easy, but in this case it works. The characters, the premise, the writing are truly amazing; his narrative description and character definition are equal to the best novelists in the trade."

"The best-written book I have read in years. This post-apocalypse story is exciting, suspenseful, and told with words and descriptions that transcend the ordinary. The weird and wonderful notions of modern theoretical physics play well into this story of bonding, survival and conflict between philosophies. As the story unfolds, human nature is shown to be the same in the new world of an oil-less future. The story is great, the narrative is outstanding, and I recommend it to anyone who enjoys reading."

"An amazingly well written post-apocalyptic book. The characters were intriguing, the pace made it a one-sitting-read. The world-building was utterly amazing, especially if you take into account that the book has some sci-fi elements in it. The plot line is very realistic. Scarily so! The most memorable thing about this book is how exceptionally well it is written. I will definitely read more books by this author."
- Wanda Hartzenberg
"Imagining a post-petroleum world and its power struggles-political, spiritual and personal-is easy with Ewing's artful prose and subtle cynicism. The characters are complex and appealing, even as they behave wretchedly. Winds of Purgatory is an engaging, thought-provoking adventure that left me yearning for more insight into the planet's Renaissance as humanity grapples with its next chapter."
- Einar Jensen
"...fresh intrigue and nonstop action when a struggle over secrets to resumed petroleum production, for better or worse for future humankind, leads to a winner-take-all battle set high in the Colorado Rockies, between historically new players. Ewing's players are not the common faceless literary cannon-fodder, but well-developed characters that make this work breathe. This work takes the reader to a different but nearby place and time, and leaves him feeling he was really there. It leaves him with a lot to think about, as well."
