Margaret Oliphant 
Beleaguered City [EPUB ebook] 
Being a Narrative of Certain Recent Events in the City of Semur. A Story of the Seen and the Unseen

Though Scottish-born author Margaret Oliphant dabbled in a remarkable number of literary genres over the course of her career, critics and fans alike agree that some of her most abiding contributions were her tales of fantasy, science fiction, and the supernatural, many of which broke new ground in their time. A Beleaguered City blends elements of fantasy and science fiction, and the end result is an astonishingly compelling read.
