Not all monsters hide in shadows. Ryann should feel safe, but everything has changed. Haven is under siege from the shades. They hide in the shadows of the forest, waiting for night, always hungry. But they don’t always kill. Sometimes, their bite infects. Cathal lies in quarantine, the infection changing his body, turning him into something else. He sleeps, as do the other infected — but sooner or later, they will wake. Then there are the men from the company. They say they have come down to Haven in order to help, but as far as Ryann can tell, they are only helping themselves. And in a company this big, individuals are of no consequence. Whichever way she turns, Ryann is besieged by monsters. The sequel to Shadowfall, Shadowsiege increases the dark tension and the capacity for evil, in monsters both alien and human.
