The discovery of alien life! What could be more exciting? Only that such life is both Sentient and communicating! For Astronomer Calandra, this discovery of hers reaches beyond her wildest dreams. Even more astonishing is that Calandra and her colleagues reside on the planet Lathos, in a different solar system...and that the alien probe sets forth from a very aggressive, cruel, global government...on Planet Earth....
I was reminded pleasurably of early Twilight Zone episodes and of Golden Age Science Fiction as author John Coon capably flips the Alien trope on its head, reversing the kaleidoscope so that Earth is the destructive alien civilization. Delightful!
