Havana Storm by Clive Cussler

Havana Storm is the latest in the action-packed Dirk Pitt series. Dirk and the gang are investigating increasing mercury levels in the Florida Straits when bedlam breaks out. Dirk and his daughter are held hostage. His crew is in danger. The ecology of the east coast is at risk. And there's an Aztec artifact that everyone and his brother is looking for--and willing to killing for. As always, it's quite the page-turner.
