You are about to discover the secrets of The Quick -

But first, reader, you must travel to Victorian England, and there, in the wilds of Yorkshire, meet a brother and sister alone in the world, a pair bound by tragedy. You will, in time, enter the rooms of London's mysterious Aegolius Club - a society of the richest, most powerful men in England. And at some point - we cannot say when - these worlds will collide.

It is then, and only then, that a new world emerges, a world of romance, adventure and the most delicious of horrors - and the secrets of The Quick are revealed.
