description: No one handled the "aliens-among-humans" theme better than Eric Frank Russell; &amp; he did it with humor and wit. SENTINELS OF SPACE describes a future spacefaring society which has colonized Mars and Venus, and is looking at the next step outward. The colonial populations are entertaining rumblings of discontent, a desire to be free from the "tyranny" of Mother Earth. As an ancillary issue, the radiations encountered during space travel have created a number of mutations, most of them involving extra-sensory powers. The flip side was the first publication of Donald Wollheim's mini-anthology-as-a-filler technique. The title story is also by Russell, a novella entitled "Design For A Great Day," here renamed "The Ultimate Invader." Also included are: The Alien Envoy, by Malcolm Jameson; The Malignant Marauder, by Murray Leinster; &amp; The Temporal Transgressor, by Frank Belknap Long.
