When portal-mage Harkon Bright and his apprentice, Aimee de Laurent, are asked to help select a new captain for the immense skyship Iseult, they very quickly find themselves embroiled in the machinations of its machiavellian officer's court. Meanwhile their new recruit, Elias, struggles to adapt to his unexpected gift of life while suffering dark dreams of an ancient terror.

As the skies darken and the storm-clouds gather on the Dragon Road, the crew of the Elysium come face to face with deadly intrigues, plots from beyond death, and a terrible darkness that lurks within the clouds of a thousand-year storm.
