When Emily Schultz, the president of Constellation Cruise Lines, buys an old cruise ship at a bargain price, she doesn't discover there's a ghost aboard until it's too late to cancel the deal. Desperate for help Emily calls upon Kayla Sanders and Natalia Baliskov to solve the crisis. The three women start a frantic search to find the identity of the ghost and her murderer. The "Lady" tries to communicate by flooding Kayla with crazy visions of the ship from her last voyage. Will the ghost's murderer kill another passenger who will be sailing on their next cruise? The entire ship is filled with suspects and potential victims, since everyone on the Sea Mist is a repeat passenger. The investigation ramps up when Kayla's fiance, Steven Young joins the ship. Suspended from his job at Interpol, Steven feels guilty and incompetent. While tracking down a smuggling ring selling black market antiquities, Steven's partner got too close to the culprits and paid with his life. Is there a leak inside Interpol? The smugglers traced Steven to Colorado, and now they know he's on the Sea Mist. Do they want him dead? Kayla must interpret her visions from the Lady in time to prevent another murder, and Steven needs to unmask the ruthless leader of the smuggling ring to get his job back. Their future depends on mutual success."
