Another novella by the incredible Brandon Sanderson. This one is a sequel to Legion, which introduces us to the mad genius of Stephen Leeds. We see again his legion of aspects, imaginary people he creates as he learns new things, solving a mystery involving biotechnology and a stolen corpse. The novella is fast paced, though a lot of the focus is on Stephen and his aspects. The more interesting parts of the story where those that touched on his interactions with the aspects and how he seems to be loosing control of them. It sets the stage for some potential future developments.
Overall, a pretty good, fast read. Reading the prior one first ([b:Legion|13452375|Legion (Legion, #1)|Brandon Sanderson|https://d.gr-assets.com/books/1338512017s/13452375.jpg|18978261]) is highly recommended.
