An Earth-based amateur radio amateur operator innocently transmitting to other hams here on Planet Earth has been detected by an alien civilization 11.7 light years away. A cascading series of events then plunges Earth into communication, cautious exploration, and then full-blown peaceful invasion and combining of two distinctly different cultures and unimagined alien animals. Three SETI books and the audiobook for the entry book one of SETI...The Search for Extraterrestrial Civilization.
