Sahara Aldridge, a young Egyptologist in 1922, is chasing down the trail of her parents through the unknown corridors of time.

But when all clues point to Ancient Rome as the next place to search, Sahara retreats into the safety of her archaeological work, cataloguing treasures from the newly-discovered tomb of Pharaoh Tutankhamun.

As the discovery of the intact tomb propels the world into a frenzy of "Tut-mania," the ever-present Jack Moretti is there to help, but what is his agenda?

And it appears Tempus Vigilia isn't going to leave her alone. The secret society has sent others, tracking her movements and asking too many questions.

Now it seems her family is in danger.

Sahara must once again put her career on hold, to find what she has lost.

But will Ancient Rome hold the answers, or only one more reason to grieve?
