Mirror Walker 1918 - G. R. Dasher - Bog

Morgan and Hannah are Mirror Walkers who are now married. They are asked to explore an old salt mine, the home of their previous adversary, and-while doing so-blunder into several mirrors that lead to World War I and two other Mirror Walkers, Josephine and Rodney. They also discover a young woman, Esther, who can also travel through the mirrors as long as someone holds her hand, and the five attempt to solve a series of gruesome murders that take place both inside the mirrors and in Hannah's home of Kazamura. The trail leads through the salt mine and in and out many mirrors, and the five ultimately discover that it is one of their own who is responsible for the killings. Hannah has a secret that is revealed, and the group's investigations eventually lead them to a commercial beach in California, where they must battle the killers and their hired cohorts.
