Leigh Brackett 
Shannach: The Last [EPUB ebook] 

Even in this grip of alien horror a man could not throw away his lifetime goal . . . and not stand idly by as endless rows of alabaster, shapes seated in their chars of stone, thought-rules this gargoyle planet from the dead blackness of deep Mercurian caverns. Leigh Brackett was the undisputed Queen of Space Opera and the first women to be nominated for the coveted Hugo Award. She wrote short stories, novels, and scripts for Hollywood. She wrote the first draft of the Empire Strikes Back shortly before her death in 1978.
