Reading the West Book Awards Nominee

The "gloriously original" ( The New York Times ) and critically acclaimed crime series starring a Chicago hitman hiding out as a rabbi in the desert suburbs of Las Vegas comes to its thrilling conclusion

Mafia hit-man-turned-rabbi Sal Cupertine is ready to get out of the life. But it's not going to be easy. His once-brilliant plan to pass himself off as Rabbi David Cohen is unraveling. Enemies on both sides of the law are hot on his trail. His wife and son are unreachable in witness protection and are probably in danger. In order to find his family, get out of the desert alive, and salvage his long-sought-after happy ending, Sal is going to have to confront some very bad people from his past.

Native American kingpin Peaches Pocotillo has wrested control of Chicago's mob family while expanding his criminal empire in the west, and now seeks to settle an old score with Sal. These two antiheroes have a history that stretches back decades, and the blood feud between Peaches and Sal will lead them to a violent showdown deep in the heart of the low desert.

As complications cast old revelations in a new light, including one that stretches back to the long-ago death of Sal's infamous gangster father Dark Billy Cupertine, Sal must team up with some unlikely allies-and confront the reality of who he has become-in this stunning conclusion to the popular and critically acclaimed Gangsterland trilogy.
