Her father may be head curator, but it is Theo--and only Theo--who is
able to see all the black magic and ancient curses that still cling to
the artifacts in the museum. When Theo's mother returns from her latest
archaeological dig bearing the Heart of Egypt--a legendary amulet
belonging to an ancient tomb--Theo learns that it comes inscribed with a
curse so black and vile that it threatens to crumble the British Empire
from within and start a war too terrible to imagine. 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!
