Welcome to the Kings of the Underworld. A multi crossover series that will take you from the streets of New York, to the beaches of California, and to the night life of Nevada. While the series contain crossovers, each is a new couple, with a new time line, story line, and their own troubles. 

If you like your romance a little dark, a hint of taboo, with some age gap, alpha claiming, and so much more, you'll love these Kings who will do anything for their Queens.
