Dead Reckoning — Sandra K. Moore

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
