The listing, Sorceress of the Witch World by Andre Norton has ended.
Paperback book in excellent condition.
Magic stands in two houses. The witch is one born to her craft, and her power is of the earth, of growing things and what is of nature. If she makes a pact with the Shadow then she turns to those things of evil which abide on earth--there are growing things to harm as well as heal.
The sorceress may be a born witch who strives to climb higher in her craft, or she may be one without the gift who painfully learns to use the Power. And again she chooses between light and dark.
Our Wise Women of Estcarp were born to their craft and I had been one of them, though I had not vowed their vows, nor taken on my breast the jewel as one of their sisterhood. Perhaps I could once have been deemed sorceress, since my learning went far beyond the simple witchcraft I could have wrought without struggle and preparation. But in folly and ignorance I had tampered with things of the Shadow and now those whom I valued above all, even my own life, were threatened by an evil which could reach them through me.
