Two unforgettable adventures of two very different heroes battling unknown evil and fighting to protect the helpless in worlds that are wondrous, terrifying, and utterly alien.
Dark Piper: Vere Collis and his friends were exploring caves on the planet Beltane when they were trapped by powerful explosions on the surface. They wandered underground for days, then found a way to the surface and emerged to find that only strange and deadly mutant creatures now roamed the surface. Where were they the only humans left alive on the planet?
Dread Companion: Hired as a teacher and governess to two young children on the planet Dylan, Kilda found that her charges had an invisible companion. She soon found that the companion was not imaginary at all when it led the children into an other-dimensional world. Though the other world has danger on every hand, Kilda follows the children across the spatial barrier, knowing she is their only hope.
