One cruise ship. Multiple kidnappers. In the dark waters of the South China Sea, a handful of Black Raven agents are the only hope anyone has of living to see Christmas.

From the back cover:

Seventy-five of the world’s wealthiest gamblers are ringing in the holidays with a high-stakes, three-day tournament aboard the Imagine. As the ultra-luxury cruise ship departs from Macau, financial risks are enormous and security is tight. Agents Sylvia (Leo) Leon and Adam (Ace) Evans lead Black Raven’s on-board team. Months earlier, they gave into feelings that caught them both by surprise. Now, Leo wants nothing more than to ignore what Ace is dying to confront.

While adversaries execute a seemingly perfect, diabolical plan, Leo and Ace operate in stealth mode to save the Imagine’s passengers. As danger tests the limits of their training and expertise, and their simmering chemistry hits a boiling point, their chances of living to see Christmas narrow. For these two best friends, the Imagine job could change everything…in more ways than one.
