When sixteen-year-old Rachav drinks the Moon Temple's forbidden wine, she hardly expects it to result in the death of a priestess. But when King Nur orders Rachav to serve the Queen of the Night—the kingdom's powerful goddess—as restitution, Rachav's identical twin, Zaron, has her own reasons for joining the priesthood and offers to take her twin's place.
But choices have consequences.
Now Rachav's family is in danger. As she uncovers the shocking reason why, she finds an ally in Salma, a brooding nomad who wields an ancient force powerful enough to destroy the entire kingdom. While the epic showdown rages above the city, Rachav plays a dangerous game of her own. Can she rescue her sister and right the wrongs of that fateful choice? Or will the king succeed and trap her in the doomed city?
