City of Dreams is the second book of a trilogy by Don Winslow that, he says, will conclude his writing career. The story picks up from the end of the last book, City on Fire, with Danny Ryan on the run from mafia rivals and law enforcement alike. He runs to California. Through various maneuverings and machinations he seems to make a deal that will ensure a comfortable and relatively safe life outside crime. Then he and and his crew get caught up in the making of a Hollywood movie based on the story of their own criminal gang, Ryan falls in love with the lead actress, and everything goes to hell. Fast-paced, lots of mob stuff, noir sex, and impulsive, reckless action. If you like the last one, you’ll like this one. Kirkus Reviews calls it enjoyable but dark:
