I loved how Arturo was slightly evil without doing things that are impossible to forgive. I didn't like how helpless Quinn was, while maintaining a bad ass attitude. I wanted her to get some of her own back, but every time I started cheering her on I'd get let down one way or another. The way Quinn kept falling for Arturo's lies was really annoying as well. 
 I think future books have the potential to be really good. The world building was unique and enjoyable and I think world building is one of the most important aspects of novels, preceded only by characterization.
