Island Adrift opens in Grand Cayman three days before hurricane Ivan makes landfall in September 2004. Christine Johnson faces the impending disaster of Hurricane Ivan alone in her apartment as her friends are all off island, including Mac. Mac is her friend and mentor whose identity remains ambiguous throughout the story. In the beginning he is missing and believed to be dead, only to make a sudden appearance. To some he is the returned Christ, to others, a wise man, and to his cousin, a threat. The action continues through the devastation of the hurricane and the troubled aftermath. Christine struggles to return order to her disrupted life with the help of Mac's provocative message and example. Island Adrift highlights the forces of chaos and unity in the macrocosm of the physical world and the microcosm of the human psyche. Ivan provides the chaos while Mac represents unity.
