The Copper Egg — Catherine Friend

The ancient Chimú believed their people came from three eggs: the rulers from a gold egg, their wives from a silver, and the workers from a copper egg.

Archeologist Claire Adams receives a mysterious package that lures her to Peru in search of a treasure-filled tomb. She must find the tomb before looters do. She's helped in her quest by old friends and by a strange connection to an ancient copper egg. Claire's ex, Sochi Castillo, has her own plans for the tomb. She has two jobs -- one within the law , one considerably outside it. If Claire finds the treasure first, Sochi is going to steal it. As Claire and Sochi are drawn into a web of intrigue, betrayal, and greed, they discover that love complicates everything.
