Plague Ship
by Andre Norton
Readers will remember Cargo master student Dane Thornson and his ill-fated ship The Sun Queen with its colorful crew from Sargasso Cosmos. Now the Sun Queen is ready for a new job and buys the right to trade on Sargol, a planet rich in exotic jewelry and precious oils, inhabited by the cunning cat people. But their fiercest rivals, Inter-Solar, got there before them. The sun queen tries to play honestly, but only after takeoff do the most desperate hours of the space trader begin. The crew is hit by a deadly, unknown disease; They are not allowed to land anywhere as the "Plague Ship", and there is an order that other ships must be destroyed in sight. With this fascinating space story, Andre Norton justifies his position as one of the best science fiction writers for young people.
