Here are two more volumes in the publisher's ongoing series of sf classics. Burroughs's Pirates was initially serialized in Argosy Weekly in 1932 and released in book form soon after. It features astronaut Carson Napier, who becomes stranded on Venus and finds himself swept into numerous adventures. The Poison Belt portrays Conan Doyle's other great creation, Professor Challenger. In this 1913 outing, the professor grapples with the problem of Earth's passing through a poisonous cloud, putting humankind's existence in jeopardy. Both books feature vintage illustrations. Great fun. Copyright 2001 Cahners Business Information.
