Plague Ship

"Plague Ship" by Andre Norton is a science fiction novel published in 1956. When the crew of the Free Trader rocket ship Solar Queen secures a valuable contract with the cat-like Salariki on planet Sargol, they seem destined for success. But after departing with their cargo of rare Koros stones, crew members begin falling into mysterious comas. Declared a plague ship and cast out as pariahs, only four young crew members remain healthy enough to uncover the truth behind the illness—and clear their ship's name before it's too late.
