In a future where humanity has scattered itself across the stars and Earth itself is now a dimly remembered place of legend, two worlds of near-supernatural strangeness challenge two naive but courageous heroes. The planet Beltane had been unscathed by the all-encompassing war of the four Sectors when Vere Collis and his friends were trapped by powerful explosions on the surface. Their leader was killed, but the group wandered for days underground to find a way to the surface. They emerged to find that they were the last human survivors on Beltane. Only strange and deadly mutant creatures now roamed the surface.

Elsewhere in the galaxy, Kilda's home planet had no place for her, so she took employment as a teacher and governess to two young children on the planet named Dylan. But she soon found that one of her charges has an invisible "dread companion" - and soon Kilda knows that the companion is not imaginary at all, as it leads her charges into an other-dimensional world resembling the legends of Faerie. Though the other world has unknown dangers on every hand, Kilda follows the children across the spatial barrier, knowing that she is their only hope. Two complete novels of two very different heroes battling alien and unknown evil, and fighting to protect the helpless in worlds that are wondrous, terrifying, and utterly alien.
