According to the Wikipedia, The Sky Crawlers series consists of 6 books, and one of them is titled The Sky Crawlers itself:
- The Sky Crawlers (スカイ·クロラ)
- None But Air (ナ·バ·テア)
- Down to Heaven (ダウン·ツ·ヘヴン)
- Flutter into Life (フラッタ·リンツ·ライフ)
- Cradle the Sky (クレィドゥ·ザ·スカイ)
- Sky Eclipse (スカイ·イクリプス)
There's also an animated movie with the same name, which is said to adapt the novel, but which novel? Is it only the The Sky Crawlers book, or the whole series?
