Stormchaser

Young Twig, who has always dreamed of flying above the forest canopy, finds himself aboard his father's sky pirate ship, the Stormchaser. As he explores his new role, long-buried plots threaten the floating city of Sanctaphrax, a hub of knowledge perched high in the sky. The city's survival depends on stormphrax, a volatile substance sourced from powerful storms, which only a ship like the Stormchaser can dare to encounter.
