In his classic guide, Wayne Douglas Barlowe's brilliant portraits bring to life 50 aliens from science fiction literature: Larry Niven's Thrint and his Puppeteer, Arthur C. Clarke's Overlord, Frank Herbert's Steersman, Robert Silverburg's Sulidor and more. Humanoids, insectoids, reptillians-even protoplasmic, gaseous, and crystalline life forms-are all faithfully and naturalistically depicted so that you can now visualize what could only before be imagined.
