Goodreads Synopsis:
When five hyper-successful women agree to appear on a reality series set in New York City called Goal Diggers, the producers never expect the season will end in murder…
Brett’s the fan favorite. Tattooed and only twenty-seven, the meteoric success of her spin studio—and her recent engagement to her girlfriend—has made her the object of jealousy and vitriol from her cast mates.
