Don Winslow - City on Fire. Stephen King likes this guys writing so much HE went as a customer to one of Winslow’s signings.
This is Irish mobsters in a gang war with Italian mafia in Providence, Rhode Island in the 1980s and was just as awesome as that sounds. Austin Butler will be producing and starring in a film adaptation of this. The way the book is it should be difficult to fuck up making a movie out of it, put I guess it’s always possible.
