Far Rainbow
"We all know what Rainbow is," began Lamondois.  "Rainbow is a planet colonized by science and designed for physical experiments.""The Far Rainbow was written at one breath, it is full of dynamics and genuine dramatism." --Literary Gazette"Science-fiction stories by the Strugatsky brothers are philosophical pieces.  They are full of action but each action is clearly imbued with speculation." --- Neva Magazine"Take the Far Rainbow, for instance.  ‘Authentic’ is the word, and this is rather unusual where science fiction is concerned." --The Young Guard Magazine
