Moments Before Dawn

This engaging novel describes the dilemma wealthy widower and aged businessman, Demetrius Fargo faced when deciding which of his two daughters should be the sole heir to his estate. Initially, he chose his biological daughter, Yolanda, the younger of the two women over her adopted sister, Zelda, who lived relatively close to him in New York City, and had been his care giver for quite some time. Yolanda lived in Tennessee and had not seen her father or sister in five years.
She had been her father's favorite. As such, she often exploited that preference and relied on him for financial support. She was consumed with greed and a determination to acquire his wealth. Zelda, on the contrary, was an independent -minded, hard working, modest, and caring individual. Her only desire while on the same Caribbean summer cruise as her sister and father was respite from the day -to -day care giving.
Yolanda, on the other hand, cared very little about her father's safety, his health, or well-being. Her only concern was his money. She was determined not to wait for years to inherit it, and plotted a scheme to make him disappear. Bartholomew Fargo, Demetrius's first cousin and long time business partner, had a similar plan and encouraged Jake, a friend and ex-convict, to join him on the same cruise.
Yolanda used her personal savings and the help of an ex-boyfriend to hire two hit- men to take out her dad. At that time, she was unaware that he had changed his will and made Zelda the sole heir to his fortune. Unwittingly, though separately, both sisters became romantically involved with the would-be assassins.
Who would decide Demetrius's fate?
Would it be Yolanda, Bartholomew, or someone else?
Would the individual or individuals be successful and get away with it moments before dawn?
