The Forbidden Tower

On the planet Darkover, a Keeper—the center of a working psychic circle, the manipulator of colossal psychic forces—has traditionally been a virgin female. Callista, powerful Keeper of Arilinn Tower, has resigned her office to marry the Terran, Andrew Carr, who rescued her from her abductors in the previous book, THE SPELL SWORD. As she struggles to throw off the years of conditioning that kept her mind and body under frighteningly rigid control, her new husband has his own battle with crippling culture shock. Meanwhile, Callista's brother-in-law Damon is conducting his own researches in an attempt to help her; his work, which suggests that a Keeper need not be virgin—nor female—could shake the very foundations of Darkovan society.
