The Falling Star

Seventeen-year-old Alexandria White only wants to go home, a wish that would be easier to pull off if home weren't thousands of years in the future and halfway across the world. Since her twin sister, Portia, touched an artifact during their history class, she's been stuck in ancient Egypt surrounded by the unknown: knife-wielding priestesses, soul-consuming Scorpions, and a destiny so terrifying she fled Egypt's capital city. Alex has been hiding in plain sight and putting her academic skills to use as a royal tutor in the Nile Delta, an area on the brink of war.
When tensions rise between clashing monarchies, everything Alex left behind-the magic that is her birthright, the danger of the Scorpions-is arriving at her door, as well as a major secret. She'll have to decide if she will flee again or take a stand and face her future in the past.
