Drifting through a party celebrating 400 years since the Spanish
Armada's successful invasion of Britain, Don Miguel Navarro - Licentiate
of the Society of Time - is shaken by the host's possession of a
flawless mask from an ancient Aztec festival. 'Imported' from the past,
the discovery signals a breach in the Society's policing of time-travel
and imminent danger to reality itself. Today, a relic out of time;
tomorrow, the rewriting of the course of history? In three
ground-breaking novellas, John Brunner weaves an ingenious tale of
diverging timelines and a battle for dominance over the fourth
dimension. The Society of Time stories were abridged when first
collected. Here, the trilogy is reprinted in full along with two
mesmerising standalone novellas: The Analysts and Father of Lies.
