Plunder (Faye Longchamp Archaeological Mysteries, 7)

Faye Longchamp and her Native American husband Joe Wolf Mantooth are working near the mouth of the Mississippi, researching archaeological sites soon to be flooded by oil. The Deepwater Horizon disaster has morphed her run-of-the-mill contract job into a task that might swamp her fledgling consulting business. Then her injured babysitter leaves Faye to work with a toddler underfoot. Thankfully, Amande, a bright and curious teen lives nearby with her eccentric grandmother. But when the girl's grandmother and her no-account uncle are murdered, Amande's prospects worsen.
