A solar system in which the end of history has already been surpassed: people allow themselves to be ruled by computer reason – ActualSanity – which keeps the community of planets in an harmonious ideal state. Political processes no longer seem to be necessary in this AI-driven, totalitarian and cosy government; instead, identity-forming collectives distinguish themselves from each other solely by subtle behavioural differences. Until a threat looms on the horizon: the Broken Hearts Collective disquiets the solar system with terrorist attacks – a development at the centre of which Marten Eliot and Emma Glendale, young head fellows of the Dolphin Collective, unexpectedly find themselves.

While searching for the fountain of youth, the three best friends Romy, Karlheinz and Magda Gustav encounter a witch. She announces that the reincarnation of Empress Elisabeth is among them. They urgently need to find out who, otherwise the ghost will strike them down. A Sisi competition ensues - after all, who wouldn't want to be Empress and the once most beautiful woman in the world?
