Listeners — James Gunn

A classic of science fiction, this book predicted and inspired the creation of the Search for Extraterrestrial Intelligence (SETI) -- the organization dedicated to the search for extraterrestrial life. A tale of contact with alien life hailed by leaders of SETI organizations and today's leading science fiction authors as hugely influential, the story appeals to both science fiction readers and the hundreds of thousands of members of various SETI organizations.
