Here it is, Tess Gerritsen's new Big Bestseller that went to number three on the New York Times bestseller list when it was published in September 06, and number two on the Sunday Times hardback bestseller list in January 07.

It's particularly terrifying in that it examines the nature of evil: are we born evil, or do we become that way? And it goes back to the Bible, and a little known ancient text - The Book of Enoch - about a race of demons or 'watchers' who were believed to be half-angel, half-mortal.

The thriller Tess has constructed around this ancient text is as terrifying and haunting as it is page-turning. Prepare for a roller-coaster of a ride!
