Time is not on Faye Longchamp's side. She and her husband Joe are working near the mouth of the Mississippi, researching archaeological sites soon to be swamped by oil. The Deepwater Horizon disaster has morphed her run-of-the-mill contract job into a task that might swamp her fledgling company. It isn't helping that an injured babysitter has left Faye to work with a toddler underfoot. An adolescent girl is drawn to Faye, perhaps because she idolizes the confident archaeologist. Young Amande is bright and curious, and a poverty-stricken life on a houseboat with an eccentric grandmother doesn't look like a good to get the education Amande deserves. When the girl's grandmother and her no-account uncle are murdered, her prospects worsen. With only two known relatives--neither of them much more respectable than the dead uncle--Amande seems destined for neglect or worse. Soon, Faye and Joe find themselves among people fighting hard for Amande's pathetic inheritance: a raggedy houseboat, a few shares of stock, and a hurricane-battered island that's not even inhabitable. Pirate-era silver coins are found and disappear. Shadowing it all is the fact that there's a murderer on the loose. But why should Faye be surprised by such shady events, here in these watery lands settled by the greatest pirates of them all? And the oil slick looms, because this country is still being plundered, after all these years.
