An airship captain battles spies, disturbing visions, and more as she races to find treasure in this swashbuckling high fantasy series conclusion. When a legendary craton is discovered, newly appointed airship captain Isabelle desZephyrs and her trusted musketeer Jean-Claude travel on a perilous mission to recover its fabled treasure for l'Empire Céleste. Bust Isabelle's leadership quickly becomes jeopardized. The dark, magical abilities she inherited give her increasingly disturbing and disruptive hallucinations. Disasters are compounded when a spy sabotages the ship, and Jean-Claude is lost to the expedition. Separated, Isabelle and Jean-Claude must each overcome a growing number of enemies—from the past, from the court, and from their own minds—and gather trustworthy friends before a rival expedition unlocks an ancient secret for their own nefarious ends.
