In this not-so-future world, self-driving cars are commonplace. A group gets together adjudicating self-driving car accidents, but only one of them is a citizen. The others are high-ranking, biased individuals. Libby is the citizen, and she’s very easy for the reader to empathize with. 

And then a hacker comes into the proceedings and takes over the cars and delivers an ultimatum to this group that will result in tragic consequences. 

I thought the reader would learn more about the characters in the hacked cars. In the first half, the reader does, but it feels that the reader spends more time with Libby in the back half. 

It took me a while to get into this one. The premise wasn’t terribly interesting to me, but I was definitely more interested in the second half.
