"The first murder in 500 years. Twenty billion suspects. One hope. For the past six months, newly chosen Green Lantern Sojourner "Jo" Mullein has been protecting the City Enduring, a massive metropolis of 20 billion people. The city has maintained peace for over 500 years by stripping its citizens of their ability to feel. As a result, violent crime is virtually unheard of, and murder is nonexistent. But that's all about to change. Hugo, Locus, and Nebula-winning author N.K. Jemisin thrusts readers into a stunning sci-fi murder mystery on the other side of the universe!"-- Provided by publisher.
