It is 2003 and Igor Bromovich has just been hired to captain the luxury steamship, SS Indigo, for an upcoming private cruise around the Caribbean. He is thrilled to be returning to work, and to a place he belongs. Assisted by a small crew of three, including Californian Zach Carter, he shelves the doubts that have been creeping into his thoughts and readies the ship for the five-hundred-mile sail to Grand Cayman. Sir James Parsons is a leading investor and businessman who is prepared to carry out his swan song, a homage to the father who never voiced his approval for any of Parsons' accomplishments. He is joined by an eclectic group of strangers to board the ship and the mystery cruise, all having received mysterious invitations to board the Indigo at St. Georges Caye, Belize, to hear about a once-in-a-lifetime investment opportunity. The passengers arrive to embark on a journey of intrigue and discovery without realizing that they all have one thing in common. Now just one question remains: When the ship docks in Grand Cayman, how many of the passengers will be left? In this gripping mystery on the sea, a reclusive and secretive billionaire invites a small group of strangers to cruise the Caribbean on a luxury steamship where they soon discover that nothing is as it seems, and that the road to hell is paved with good intentions.
