Warlords of Utopia (novel)

Publisher's summary
Marcus Americanius Scriptor’s memoirs of the war between every parallel universe where Rome never fell and every parallel universe where Hitler won the Second World War have long been regarded as the definitive account of that turbulent time.

Scriptor’s life story, from his early life among the housesteads of an obscure province to his role in the ultimate confrontation with Nazism, was intimately connected with the major political and social developments of his time. His highly personal record of events was praised even in his own lifetime for its honesty and intimacy, as well as for capturing the scale of a war that consumed thousands of worlds.

This exciting new translation of a classic work of military history is accessible to new readers and existing students of the War alike.

Continuity

 * Marcus kills an enemy agent (or possibly even an Enemy, it's left ambiguous) by stabbing it because it's not prepared for such a simple and primitive attack. This harkens back to PDA: Heart of TARDIS, where the Brigadier destroys the physical body of a daemon because it's not concentrating on keeping it's form solid and the shock of physical contact is enough to disrupt it's form and further back to DW: The Pirate Planet where the Doctor says the more sophisticated a mechanism is, the more susceptible it is to primitive attack.
 * Marcus ends up on "Earth Prime" (the Earth of the Faction Paradox universe), and receives help from a mysterious traveler, who may be "the evil renegade" of Great House lore (ie: the Doctor).
 * There are clockwork sailors on Roma-I (the Prime Rome world) similar to the Clockwork Droids in DW: The Girl in the Fireplace.
