Watchers of the Dawn (A Steampunk Adventure)
by Stephen Schrum
While searching for the First Vampyre, whose minions destroyed her hometown, Aemelja Umber encounters Stephano Alchimi, an immortal alchemist. She joins him and his order, the Vigilum Aurorae (the Watchers of the Dawn), who seek to end the source of ultimate evil in the world.
WOTD is also an allegory: of corporate America, the promises/pitfalls of science and technology, and consumer culture.
