Now a chain-smoking, self-destructive alcoholic, Jessica is the owner and sole employee of Alias Investigations, specializing in superhuman cases.

Or has she burned too many bridges to turn to old friends for help? Plus: Jessica investigates the disappearance of a girl rumored to be a mutant, pursues an awkward relationship with Luke Cage, and teams with Jessica Drew to investigate a drug that grants super-powers! But when a nightmare returns, can Jessica find the inner strength to defeat the demons of her past?
