When a monster from myth threatens the cardinal world of Ophelia VII, Morvenn Vahl defies the Senatorum Imperialis and heads to the planet's defence. There, she finds a world in terror – the warlord Kol Rakhul, known as the Death of Saints, has come for the faithful and, with his Heldrake and a host of Night Lords at his back, plans to enshroud the world in flame and blood.

This is a reckoning. A holy world is being defiled, and in its defence, Morvenn Vahl must wield an army of Living Saints to stand a hope of survival, let alone victory.
