A young reporter in 1923, Alma Reed accompanies archaeologists to the ruins of Chichen Itza, where a fortune in Mayan artifacts has been stolen from a sacrificial well. It's believed a curse was unleashed by the theft-yet the career-making story it offers the ambitious journalist seems a godsend. It also leads her to a passionate love affair with revolutionary governor Felipe Carrillo Puerto. But when fate darkens their lives and damns them as doomed political pawns, Alma can't help but wonder if the curse is not, in fact, very real.

In another century, another writer is fascinated by Alma's tragic story. Drawn restlessly to Yucatan-and away from the stifling needs of her desperately ill partner-Sage Sanborn is tempted by her growing feelings for David, a scientist who encourages her to delve deeper into Alma's history. And in this ancient place of mystery and spirits, Sage must make an impossible decision that will forever change the course of her life.
