"Intrigue, espionage, engaging characters, a clever backdrop and an intelligent conclusion, what more could you ask for in a thriller. This one singes and tingles with heaping doses of adrenalin. Enjoy." Steve Berry, #1 New York Times and Internationally Bestselling Author "Stacy Allen writes adventure as one who has lived it. In Expedition Indigo, the tension, suspense and action come across in an incredibly real and personal way. Her heroine, Riley Cooper, is a great addition to the literary world of explorers. Genuine, innocent in some ways, and brave, a welcome change from a world of hardened heroes with dark pasts. I cannot wait to read more of her adventures." Graham Brown, author of The Eden Prophecy Archaeologist Riley Cooper is offered the chance of a lifetime: a chance to find the Crux Fidelis, the coronation cross of Charlemagne. Under Water Sea Adventures members believe they have found the remains of the Indigo, a heavily laden cargo ship commissioned by Charlemagne and presumed lost on its maiden voyage off the coast of southern Italy in the early 800s. If Riley can find the cross, it will prove Charlemagne's coronation as the First Holy Roman Emperor by Pope Leo III on Christmas Day had not been a spontaneous act, but rather a desperate political maneuver by a Pope in need of protection. When Riley joins UWSA off the coast of Sorrento, Italy, tensions and tempers fly as a competing team arrives in search of the treasure and an approaching hurricane gains strength and heads straight toward the dive site. And when one of the crew is murdered, Riley must find the strength to fight back and keep the treasure out of the other team's hands."
