John Twelve Hawks has revealed that he has finished his next book in the Fourth Realm Trilogy. The Dark River as its name is will be published by Doubleday in the summer of 2007.

"I’ve always seen the trilogy not as three books, but as a very long novel with an international setting. The action of The Dark River will take place in New York, London, Berlin and in a variety of other unusual locations. My goal is to show familiar places in a way that may surprise some people." John Twelve Hawks

He has also revealed that the Irish Harlequin, Mother Blessing, will be a crucial part of the conflict between the Tabula and the Harlequins and that some of the characters won't survive the whole trilogy.
