Dead Reckoning

Notes from the Captain's log: My destination: An island not marked on any map My mission: To rescue my sister from her drug lord husband, come hell or high water But first, I need to figure out which of the undercover DEA agents aboard my ship-men sworn to protect Natalie and me-is a traitor. I'd been poisoned by exhaust fumes and nearly sucked into propeller blades-and these were no accidents.
Unfortunately, the agent I took into my confidence-and into my bed-has been lying to me all along. Suddenly, navigating the good guys from the bad is a lot harder. But I'm one mistress and commander no one wants to cross.. -Captain Christina Hampton, the Obsession
