The Darkness Below

Book excerpt: Dr. Harriet Marks has advised the British security services on science for too long, when even gathering forensic evidence at a remote science-terrorist safehouse arouses little professional excitement. But as a snowstorm closes in, her team realise they’re not alone. While some dangers might have once been human, there’s also a darkness below that’s less recognisable. A darkness as potentially dangerous as the one already within her. A speculative novella.
