KIYA: Hope of the Pharaoh (KIYA Trilogy #1)
Katie Hamstead

The Great Queen Nefertiti despises Naomi instantly, and strips her of her Hebrew lineage, including her name, which is changed to Kiya. Kiya allies herself with Horemheb, who pushes her to greatness and encourages her to make the Pharaoh fall in love with her. When Akhenaten declares Kiya will be the mother of his heir, Nefertiti, furious with jealousy, schemes to destroy Kiya.
Kiya must play the deadly game carefully. She is in a silent battle of wills, and a struggle for who will one day inherit the crown. If she does bear an heir, she knows she will need to fight to protect him, as well as herself, from Nefertiti who is out for blood.
