Gu is a science fiction novel in more or less the style of Charles Stross, by Mike Reeves-McMillan.
Gu is the Protean substance, the last industrial product, the stuff that can be anything, can morph into any shape. Susan Halwaz, the famous maker of digital-experience documentaries, is tracing the human story of the development of Gu. You experience this story through her eyes and the eyes of the people she interviews.
