Lady Anne Worthington has traveled to the land of pharaohs, pyramids, and ancient inventions in search of missing flygirl Delaney Kincaid. Finding the adventurous young woman gets more complicated when Anne discovers Delaney isn't merely missing—she's wanted for murdering her fiancé.

The evidence is rather inconvenient. Nikolaos Zorbatos was stabbed with an ancient iron dagger, Delaney has vanished, and someone seems determined to make certain she takes the blame. Armed with her latest inventions and an insatiable curiosity, Anne joins forces with an old friend, Penelope van Kessler, to follow Delaney's trail through Egypt's tombs, dig sites, and antiquities.

But the deeper Anne digs, the older the secrets become.

A clue to Delaney's whereabouts points toward a past the missing flygirl knows nothing about and the people who have spent more than twenty years trying to find her. Following it could lead Anne straight to Delaney. It could also reveal that Delaney Kincaid isn't who everyone believes she is.

Can Anne uncover the truth without exposing the woman she's trying to save? Or is this one mystery better left buried beneath the sands?
