Reading High Steel by Jack C. Haldeman II and Jack Dann was like breathing pure oxygen…. Various imagined futures—from hard sf through Cyberpunk—intersect en passant in narrative sequences of astonishing equipoise and thrust…. Most of the book is a predator, like a cat with blazing eyes, gorging on the good meat of genre: Dick, William Gibson, Gred Bear (for transcendental AI-shamanism shticks here very succinctly conveyed), Joe Haldeman, many others. There are aliens, and Jupiter, and FTL, and Einstein the AI god, and ghost dances, and marrying out and New England School of Ethical Romance sehnsucht à la Richard Grant and Co, and a kitchen sink. And it spins high and dry and off the end of the last word. It is most highly recommended. (John Clute, editor of the Science Fiction Encyclopedia)
