Soulfuel (Warhammer 40,000)

A horror is loose on the holy shrine world of Sanctus Shibboleth. Xenobia Nox – witchbreed, monster, deadly rogue psyker who has cut a path of destruction across three worlds – is tearing down the temples to Saint Jeronimus. But her time is numbered for the Battle Sisters of the Order of the Ebon Chalice are in pursuit. But the capture of the witch may just be the beginning of Palatine Adrianna Verlatz's problems, as the Red Corsairs circle, awaiting their moment to strike… Read it because
It shows the lengths to which both the Emperor's warriors and the forces of Chaos will go to capture a powerful rogue psyker – and the very different uses to which they might be put once in custody.
