Anderax Grayvenhorn has spent his whole life traveling to the aircities in his parent's dirigible, with one dream... to climb a real tree.
When his father, an aircity inspector, is sent to learn why these floating towers are starting to slip through the clouds, Anderax discovers the dark truth of their power source, and is pursued by the soul-stealing Archangels. As tensions rise, he finds the key to saving the aircities and the dragons is not a destiny of war, but to become one of the legendary Peacecrafters.
