This was somewhere in the 2008-2009 time frame. I'm pretty sure my dad gave me this book after he read it, and he read a lot of Clive Cussler-esque books (i.e., adventure possibly including sci-fi elements).
The main thing I remember is that there was a scene where some characters were either waiting for or introducing another character who they called "the Haitian". One of the characters responded by asking "what kind of -nese is he?" or something similar, in the sense that she thought he was called "the Asian" instead of "Haitian".
This might be me confusing this with other books I read at the same time, but I want to say the story was about finding Atlantis.
