From the cover: "In his obsessive quest to keep his forest at peace the druid Argus has sought for and gained access to the Liber Mortis. That dread book of the undead has long been a bane to men, for within its dusty pages lay eldritch sorceries of the gateways and worlds beyond the minds of men. And Argus' lust has led him astray, corrupting him and making of him a monstrosity and so he has turned his own precious forest into a land of dread fey and terrible nightmare. So the Dryad Eva has come to the Halls of Men seeking aid for her kind and her forest."
