A Nomad of the Time Streams: A Scientific Romance [signed] [first edition]

Strange worlds occupy the infinite multiverse. They are worlds very much like the Earth we know--worlds that but for a vew differences could be our own. Visit an Earth where historical fact is turned on its head; slavery remains a practice in the United States. This is the fourth volume in the epic. Includes The Warlord of the Air, The Land Leviathan, and The Steel Tsar.
