Three Against the Witch World
Author: Andre Norton
 
To the north and west and south the boundaries of Estcarp were marked and known, but eastwards lay mystery. North, west, south and east . . . the offspring of Simon Tregarth, half earthling, half witch-brood, realised that they alone could perceive the four directions - for everyone else, there was no east. It was a blank in the mind, a blank in legend and history.
And when new menaces threatened, the three who were one, Kyllan, Kemoc and Kathtea, perceived that in that mental barrier lay the key to their world. Somewhere to the unknown eastward must lie the sorcery that had secretly moulded their destinies.
