Intent on returning the malevolent artifact to its rightful place, Theo devises a daring plan to put things right. But even with the help of her younger brother, a wily street urchin, and the secret society known as the Brotherhood of the Chosen Keepers, it won’t be easy . . . she quickly finds herself pursued down dark alleys, across an ocean, through the bustling crowds of Cairo, and straight into the heart of an ancient mystery. Theo will have to call upon everything she’s ever learned in order to prevent the rising chaos from destroying her country--and herself!
