Verity Darkwood and Gareth Winter have finally found some peace. Their business is thriving, they have a new home base, and Verity has finally established a relationship with her estranged father. But when she begins having visions of Samuel Bell, the man who killed her sister-a man who has been in a coma for over a year at Strongpoint Psychiatric Prison-she and Gareth fear that their battle with John Berith, The Seventh Devil, may not be truly over. When the mysterious Mort Sterven confirms that Berith is indeed unvanquished and gaining strength in order to find his next Vessel, Verity and Gareth must risk everything and everyone they love to defeat him once and for all.
