Sadness Belongs to the Universe

The novelette is set in the distant future where humans expended their influence on the solar system and far from its conventional borders. An engineer Wilfred lives and works in China. His life consists of his job, his beautiful wife and trips to the place named “island”.
Since the beginning the earth was protected by Seven aliens who arrived to the planet each time there was any threat to it, but recently the tunnel between two realities they used was closed. Wilfred agrees to construct the new one. At the same time out of nowhere the woman named Anna appears in his life. Interaction between Wilfred, his wife and Anna reveals their common past, shaped future and ancient connection between Wilfred’s past life decisions and the tunnel that was recently closed.
