A barnstormer. A Wild West trick shooter. A mathematician.

When archaeologist Anna Baring announces the founding of the Lady Adventurers Club in May 1923, none of the other three members expect to ever meet again. After all, they live halfway around the world from each other. What could possibly bring them together once more? Then they each receive an unexpected letter. Anna has found a tomb that promises to be even grander than that of King Tutankhamun, and she wants them to come to Egypt for the opening.

It's the find of the century. The tomb will make old Tut look like a pauper. But will the women of the Lady Adventurers Club get to see it? Egypt is a political powder keg. Unscrupulous criminals keep shooting at them. And weird, unnerving things seem to happen wherever they go. As the women race across Egypt, their friendship will be tested as they fall deeper into danger. They're not the only ones after a pharaoh's treasure.
