John Sinclair: Demon Hunter Volume 4 (English Edition) by Jason Dark

It doesn’t take long in the demon hunting business to realise that not everything is as it seems. When a madman is found wandering the woods in Spessart, John Sinclair finds himself at a fairy-tale castle promising its patrons a night they’ll never forget. Little does he know, something far more sinister lurks behind closed doors. An unholy plan to unleash the horrors of a long-lost continent leads Sinclair to team up with his partner Suko, but time is of the essence. Can the infamous Demon Hunter take on the unstoppable force that is the Black Death, or will he lose his head along the way?
