Steal Across the Sky, by Nancy Kress, is a sci-fi book about the effect an alien race, the Atoners, have upon humanity. Showing up in the not-very-distant future, they state that they have committed a crime against humanity, and ask people from all over the world to submit applications for the opportunity to go to space in order to witness their crime. A few dozen people are chosen, and of them, only about six come back to Earth having actually witnessed the crime. The story focuses mainly on four characters and how they deal with the revelation. When they had returned from space, those who had witnessed the crime inform their governments and people of what they had witnessed, and this although leads to radical and terrorist groups springing up, for the most part, it does not greatly affect the society that the characters are living in or how it runs. Interspersed throughout the book are ads and, at some point, an email, that take the scope of the story away from just the characters and show the Atoners’ impact on (mainly) the U.S..
Personally, I found that the book started off strongly, and at first I was going to stop reading, but I wanted to find out what crime the Atoners had committed. Then, after I found out, I kept reading because the author didn’t reveal what remedial action the Atoners had promised to take for their crime until the very end of the book. The one thing that really bothered me about the book was that the author never revealed why the Atoners had come to Earth and committed their crime, but otherwise, I thought the plot was unique and well-written.
