Ghosts of Empire

In the aftermath of the events seen in Ghosts of Karnak, and with the political climate somewhat eased, Gabriel takes Ginny to London by airship to recuperate. But he isn't counting on coming face-to-face with a man who claims to embody the spirit of Albion itself, sinister forces gathering in the London Underground and an old ally - the British spy, Peter Rutherford - who could desperately use his help.
