Salvation comes, unexpectedly, in the form of a telegram from Eldren Llewellyn a Welsh lord and the sole owner of a mining empire. He'd partnered with her father in multiple business ventures, and upon the man's death, proposed to Adelaide in order to spare her the ordeal of returning home in her stepmother's less than tender care. But as she travels to his remote estate in Snowdonia, Adelaide comes to realize that his ancestral home, Cysgod Lys, literally the Shadow Hall, is filled with secrets and dark things she cannot name. Fear is her constant companion and she begins to wonder if her new husband is her savior... or her doom.
