The Untime — Hugh Ashton

On his return from the Untime, described in the previous book in this series, Jules Gauthier, 19th century Parisian journalist, marries Agathe Lamertine, daughter of Professor Lamartine, the original discoverer of this mysterious state beyond time and space. Has Agathe really lost her father? An outbreak of nightmares in Paris, leading to madness of the dreamers, persuades Jules and Agathe that Lamartine is still alive, trapped in the Untime together with monsters intent on taking over our world. Summoning all their courage, Jules and Agathe, accompanied by the faithful Louis, and supported by Professor Schneider, return to the Untime to seek Lamartine and defeat the horrifying creatures that exist there. But all is not as it seems...
