In the sequel to "Summer's Portal", twins, Ombline and Georgianna Patrone on hiatus from their successful lives in London look forward to spending time in the small New England coastal town of Smugglers Cove amidst Autumn's beauty. Almost immediately an abandoned old house, Dragons Roost, high on a ridge outside town is the catalyst to their being participants in high adventure-solving a mystery centuries old-one so astounding, its solution will change the course of the human race. A parallel world not unlike Earth propels the Patrones' into becoming part of a small clandestine group that has for centuries planned for the liberation of Earth from a darkness so vile and devious its presence has never been suspected by the masses. Many characters from "Summers Portal" take up the gauntlet initiating the climax to come as their combined efforts will determine the future of all humanity.
