The rollercoaster whirlwind emotional journey of Scarlett Nyx and her horsemen has come to a violent and satisfying conclusion. All the answers we sought since Carnage will be answered. 
I binged this series in 24 hours, and I have been unable to engage in a series since genuinely. Sarah destroys us all with her characters, their flaws and their strengths. How she manages to spin genuine humanity into her characters defines her growth as a writer.

Also, we all get the incredible and satisfying resolution to #StuartAndMasonMustDie -- I may have highlighted those passages for when I need to fulfil some homicidal desires, because of the pacing, the emotion, urgh it's everything.
