THOU SHALT NOT SUFFER A WITCH - OR WARLOCK - TO LIVE! Beyond science and sorcery, time and space, the enemies of peace once again come to the planet Gramarye. Their mission: to tempt the clergy with visions of power, and lead them to war against the throne and establish a theocracy. Only warlock Rod Gallowglass can stop it - or burn at the stake for trying...

Protecting the planet Gramarye from a band of renegade sorcerers, the Gallowglass family suffers a weakening in their collective psychic powers, forcing warlock Rod Gallowglass to confront his own innner rage.

Five hundred years from their own time and place on the magical planet Gramarye, Rod and Gwen Gallowglass are held captive on another planet - a world where purple-skinned, fur-kilted men challenge them in primitive battle. Lost within time and space, Rod and Gwen must fight for their survival, freedom, and to return home.

HOW CAN YOU FIGHT YOUR OWN MADNESS? Rod Gallowglass, Lord High Warlock of Gramarye, has gone mad. Lost in hallucinations, fighting monsters that aren't really there, he's a danger to his family and himself. Has he finally lost his mind? Or have his adversaries found a way to not just destroy him, but discredit him as well? Most of all, how can he find his way back to sanity? With a handful of allies real and imagined, battling enemies part real and part delusion, can the warlock win a war on the battlefield of the mind?

A FAMILY LOST IN A WORLD OF MAGIC AND MONSTERS A scientist from Earth at heart, Rod Gallowglass has come to terms with the “magic” of the medieval lost colony planet of Gramarye, and is just beginning to understand his own powers. But when his enemies lure his family through a portal into what appears to be an alternate universe, he must follow them into a world where magic really does seem to work and where the laws of the universe seem to have been rewritten. Reluctantly drawn into a dynastic conflict, hunted by monsters both faery and human, can Rod and his wife Gwen keep their children free and safe, let alone find a way back to their home world of Gramarye? Bringing his renowned blend of science fiction and fantasy back to the world of Gramarye, Christopher Stasheff once again redefines what is real and what is “magic.”

When the townspeople of Gramarye become mesmerized by the beat of strange floating musical crystals, Rod Gallowglass sets out to uncover their mysterious origins before he loses his children to their sinister charm.

THE FATE OF A KINGDOM RESTS ON FOUR CHILDREN The Kingdom of Gramarye is spiraling into chaos, and the High Warlock is nowhere to be found. With their parents suddenly and suspiciously vanished, the four Gallowglass siblings - Magnus, Cordelia, Geoffrey, and Gregory - are all that stand between peaceful order and violent anarchy. But how can mere children, even with an elfin babysitter, stand against dragons and giants, witches and sorcerers? With armies on the march and monsters on the prowl, these four brave kids must work together and combine the skills of their mother's magic power with their father's training in order to save the kingdom... but only if they can save themselves first!
