The Adventures of Luther Arkwright

Luther Arkwright is a work of apocalyptic science fiction set in parallel universes. The eponymous hero has the unique talent of being able to move between parallels purely by force of will, and is aided by Rose Wylde, a telepath whose many incarnations across the parallels are able to communicate with one another. Luther and Rose are agents of a parallel known as "zero-zero", whose stable position in the multiverse has allowed the development of a world at peace with itself and sufficiently high technology to monitor the parallels for signs of the malign influence of the "Disruptors".

Most of the action in the story is set in a parallel world where the English Civil War has been indefinitely prolonged by the actions of the Disruptors, who are also responsible for unleashing "Firefrost", a legendary artifact which is destabilising the multiverse. Arkwright intervenes on the Royalist side in order to draw out the Disruptors and locate and destroy Firefrost. Along the way his unit is ambushed, and he is killed, only to return to life with his powers enhanced.
