I enjoy these old pulps. They are more speculative (dare I say 'intelligent'?) than many of the action-packed explosion-fests that pass for science fiction today. This one includes the first half a two-part story about a symbiotic alien that crashes on Earth and occupies a boy. There's also a story of alien visitation by Poul Anderson and one about an intentionally 'lost' interplanetary war by Isaac Asimov. All quite imaginative. Lost Ulysses, by William L. Bade, is an odd tale about planetary colonization, which hinges on the strange time dilation of traveling faster than light. ( )
