Kat Lightfoot thought that getting a job at the famed Tiffany’s store in New York would be the end to her problems … She has money, new friends, and there’s even an inventor working there who develops new weapons from clockwork, and who cuts diamonds with a strange powered light. This is 1862, after all, and such things are the wonder of the age. But then events take a turn for the worse: men and women wander the streets talking of ‘the darkness’; bodies vanish from morgues across town; and random, bloody attacks on innocent people take place in broad daylight. Soon Kat and her friends are fighting for their lives against a horde of infected people, with only their wits and ingenuity to help them. A steampunked story of diamonds, chutzpah, death and horror from the blood-drenched pen of Sam Stone.
