After solving a massive case, Amara Alvarez got the promotion she was seeking to San Ontonio’s Homicide Division. Her first case, a teenager found dead at a water park from what looks like a combination of alcohol and heatstroke, doesn’t seem too difficult. As she looks into how he could have died, it turns out something much stranger is going on. But who would kill someone at such a public place? The first book in this series, Collision of Lies, took a case that looked simple enough and turned out to be something large and labyrinth-like in its complexity. Here, the case goes inward rather than outward, a murder that eventually leads into questions about internet hacking and loss of privacy. So, Threadgill reverses the formula, and it does it quite well. He manages to make a story with a smaller cast and smaller scope feel just as dangerous as Collision of Lies (which is pretty impressive, since the earlier book followed a conspiracy across multiple countries).
