Wexler's principal epic fantasy series, "The Shadow Campaigns", is set in a world resembling Europe and North Africa of the Napoleonic era. It mainly follows three soldiers of the kingdom of Vordan – Count Janus bet Vhalnich, a character patterned on Napoleon, Marcus d'Ivoire, a seasoned infantry commander posted to a backwards colony, and Winter Ihernglass, a young woman who disguised herself as a man in order to be able to enlist. In "The Shadow Throne" the series introduces a new main character, Princess Raesnia Orboan of the Vordan kingdom. As they struggle through Vordan's equivalents of the French Revolution and the attendant wars, they also face a supernatural threat in the form of conspiracies fighting for control of the rare remnants of magic still existing in the world.
