In this final AIR volume, Blythe returns to work to find a surprise: the Hyperwing 307, the sleekest and most advanced airship ever built. It will be hers to pilot if she survives a series of baffling tests.
Then, on her way to a final confrontation with the Etesians, Blythe must untangle a mystery surrounding the disappearance of legendary aviator/author Antoine De Saint Exupery and discover the hidden meaning of a lost manuscript by Jules Verne.
