The following synopsis is presented in chronological order, although it is not presented that way in the novel. It is the year 2025, and many world problems (such as overpopulation, economic depression, resource depletion, racism, and crime) are on the verge of being solved. Robert MacDonald is a 47-year-old
linguist and
electrical engineer who is director of The Project, an attempt to listen for attempts at
interstellar communication. For 20 years, he has been married to Maria, a Hispanic woman from
Puerto Rico. MacDonald is obsessed with his job, which places strains on his marriage. His wife, who has previously attempted suicide by taking an overdose of
sleeping pills, slashes her wrists in a second attempt. Although MacDonald almost resigns to care for his wife, he does not. Two years later, MacDonald and his wife have had a child, Robert MacDonald, Jr. (known as "Bobby"). MacDonald is interviewed by a journalist, George Thomas. Thomas is skeptical of The Project's cost. He also confronts MacDonald with the views of a new Christian sect, the Solitarians, led by the elderly preacher Jeremiah Jones. Jeremiah (he prefers to use only his first name) believes that humanity is alone in the universe, and that the search for extraterrestrial intelligence borders on
heresy. That night, as Thomas visits the MacDonald household, The Project receives a message from the region of the
star Capella in the
constellation Auriga. The message is badly degraded by static, but appears to be early radio and audio-only television signals beamed back at the Earth from an alien race. MacDonald releases the news to the entire world. The Project computer slowly begins assimilating the Capellan information, secretly becoming more Capellan-like, as humanity turns inward again and starts to learn about the dead Capellans. The story ends with the revelation that, 50 years later, another message is received from the
Crab Nebula. ==Development==
