An extraordinary novel of magic and mystery from two of fantasy's most electrifying young authors. This wild romp leads readers through every corner of mid-nineteenth-century England, from the parlors of the intellectual elite to the dens of the underclass. Not since Wilkie Collins and Sir Arthur Conan Doyle has there been such a profusion of guns, sword fights, family intrigues, women disguised as men, secret societies, occult pursuits, philosophical discussions and sheer adventure!
