X-23 on a journey to find herself - the demon Wolverine told her because she was grown in a lab she doesn't have a soul, so she decides to leave the X-Men for a bit and find out for herself if that's true. The first person she comes up against is Miss Sinister, who, as a genetic experiment of Mr. Sinister's, is having similar thoughts - except her thoughts are expressing themselves very violently, and X-23 has to figure out a way to stop her. Guest-starring Gambit!
