SRM

There is a basic tenet of human science that the Universe is homogeneous, that is, that the physical laws which we observe and have deduced from our vantage point on Earth are applicable throughout the whole of space-time. Turns out not to be true: our own planet has just entered a zone of space where there is an excess of anti-entropy, where certain sorts of things are just as likely to run up as run down.
This has happened before, approximately two point two billion years ago, at which time the surface of the planet was still naked hot rock. On that accasion, the excess anti-entropy caused simple enzymes, proteins, and yes, deoxyribonucleic acid to form on Earth. It was the start of Life.
This time, however, the Earth is a much more benign environment. Human beings have made electronic fuel injected internal combustion engines and pocket calculators, and with raw materials already so organized, the effect of the anti-entropic zone is startling. Our highly engineered waste conglomerates into small, mobile life-forms. self replicating machines. The characters in this book try to get on with their lives while the SRMs tear our fragile, technology-dependent civilisation apart.
