A sunken treasure ship, dangerous smugglers, and a hot guy who's stuck with me- what could go wrong?

I have only ever wanted one thing: to find the Santu Espiritu, a five hundred year old Spanish treasure ship wrecked somewhere off the Texas Coast. When my grant funding evaporates, though, I'm risking more than my professional reputation: finding the treasure was my father's lifelong wish, too. The father I thought was my best friend, until I'm in a hit and run with a hitman, and Dean, a swaggering stranger, commandeers my boat. With me in it- and I find out there's a whole lot I didn't know about my dad.

According to Dean, my father wasn't a fishing guide, but a drug trafficker. Dean Evans suspects I'm the key to finding a massive shipment of narcotics- me! A freaking history professor, whose idea of a getting lit involves eating cheese and crackers on the fancy plates on my couch.

I have no idea where the drugs are, though Mr. Ex-Marine Dean and the traffickers missed that memo, since they're still chasing us. But when I realize my dad left a series of clues to a location smack dab in the middle of the Gulf of Mexico, I assume the Santu Espiritu is wrecked out there. Dean thinks it's the lost narcotics shipment. To find either, we'll have to work together, outwit the bad guys, and ignore our lust for more than Spanish gold.
