The Nightmare Factory: Rise of the Shadowmares

Andrew and his twin sister, Poppy, thought they had defeated Vesuvius, the master of the Nightmare Factory, once and for all. They were wrong. Now his power is rising, and his army of Shadowmares have managed to cross to Earth. They rule the night, feeding off humans' fear in 'fear farms' where they have build hundreds of fear pods. Andrew learns that the only way to stop them, and stop Vesuvius, is to find an ancient artefact, the Fender's feather, which holds enough magic to power a dream catcher for Earth.
The mission will be long and difficult, and time is running out...
