Eversion 

Eversion is a superb, original Gothic SF novel. A small group of intrepid explorers are in search of a remote and mysterious artefact. It’s a well-funded expedition, well organised, which is lucky as they’re sailing north of Bergen on the schooner Demeter, searching for a narrow inlet which will lead them to a vast uncharted lake – and their goal –Until disaster strikes.Doctor Silas Coade wakes from disturbing dreams, on the steamship Demeter, in pursuit of an extraordinary find almost too incredible and too strange to believe, secreted within a lagoon in the icy inlets of Patagonia. But as they come in sight of their prize he and the crew see they are not the first to come so far: there is a wreck ahead, and whatever ruined it may threaten them as well–Shaking off his nightmares, Doctor Silas Coade joins his fellow exploders on the deck of the zeppelin Demeter and realises something has already gone dangerously wrong with their mission. If any of them are to survive, then he will have to take the exploration – and their lives – into his own hands . . .
