Death's End (Remembrance of Earth’s Past, #3)

by Liu Cixin

Cheng Xin’s eyes moistened. She was thinking of Tianming, of the man who struggled alone in the long night of outer space and an eerie, sinister alien society. To convey his important message to the human race, he must have racked his brain until he had devised such a metaphorical system, and then spent ages in his lonely existence to create over a hundred fairy tales and carefully disguise the intelligence report in three of those stories. Three centuries ago, he had given Cheng Xin a star; now, he brought hope to the human race. Thereafter, steady progress was made in deciphering the message. Other than the discovery of the metaphorical system, the effort was also aided by another guess that was commonly accepted, though unconfirmed: While the first part of the message to be successfully deciphered involved escape from the Solar System, the rest of the message likely had to do with the safety notice. The interpreters soon realized that compared to the first bit of intelligence, the rest of the information hidden in the three stories was far more complex.
