Hardback in Good clean condition

A Terran Mapping and Exploration aircraft crashed on the other side of the mountain range that circles the planet. It was presumed there were no survivors and the plane lost. It was presumed so until Alexis Anders walked back into Thendara unscathed, but without her memory. Cholayna, the Head of Terran Intelligence on Darkover, called in Magda Lorne to help her figure out what happened. Magda Lorne, a legend in the Intelligence field, is not simply an intelligence agent, but rather someone who was raised on Darkover from childhood and possesses the "laran" psi power that would allow Magda to see into Anders' mind and find out what happened to Anders. Magda is more than an intelligence agent, she is a woman who has "gone native" and is a member of the Order of Renunciates, an organization that gives women another choice of what they can be in this incredibly patriarchal society. What Lorne finds in the mind of Alexis Anders shouldn't be possible. By all accounts, there is nothing on the other side of that mountain range. Nothing. Satellite photos show nothing, and it is common knowledge on Darkover that nothing can survive over there. Yet, the mind of Alexis Anders reveals the existence of a hidden city deep in the mountains, a city where there are women of power who are wearing robes. This may not seem too exceptional (except for a city existing where one shouldn't exist), but from the previous novels which feature Magda Lorne, we know that in a couple of instances using her "laran" Magda has encountered strange women wearing robes on the spiritual plane who have called themselves the "Dark Sisterhood". She originally dismissed this because there was no confirmation that what she thought she saw was real, but with this additional confirmation from Anders, Magda believes there truly is a Dark Sisterhood. When Alexis finally regains her memory, she secretly commissions a guide to find this hidden city. Magda figures out what is happening and that Alexis is attempting something that she does not truly understand, Magda, along with her freemate Jaelle (another character we are familiar with by this point), and a couple of other women (including Cholayna and Camilla) try to track Alexis before she can find the city (or die trying to find the city).
