Books in the Fiona Carver series

"Fiona Carver has landed a dream assignment: conducting an archaeological inventory of Ruby Island, a privately owned, pristine gem in the Caribbean. Two months in paradise exploring and mapping a lush rainforest, vast caves, and a seventeenth-century star fort and following up on legends of hidden Spanish gold. Add a simmering reunion with wildlife photographer Dean Slater and it's enough to take Fiona's breath away. But the sparkle fades when Dean's arrival is met with sudden, terrifying danger. Reunited and determined to see the project through, Fiona and Dean find themselves in a swirl of intrigue as they delve into the complex history of the unspoiled refuge, now a tropical haven for billionaires and their secrets. But the work isn't easy, as someone appears determined to kill the project--by any means necessary."--Page 4 of cover
