Gridlock - Nathalie Gray
Sometime in the future, the computer, after continuing to gather knowledge, takes over "The Grid." Most people are chipped which allows identification (and tracking). Dante has been experimented on. Horribly and frequently. Until he escapes. He uses his time, while free, to plot his revenge and crime-fight.
Steele is an interesting character. She has multiple tattoos and piercings. I liked how layered she is, there's a lot more than seen on the surface. As well as with Dante. For a novella this was well done with the pacing, plot, and yes, Dante's revenge. I enjoyed that.
