Daughter of Sparta by Claire M. Andrews
Daphne has spent her entire life honing her body into a weapon and her heart and mind into stone, in order to be accepted by the unyielding people of ancient Sparta. But unrest throughout ancient Greece, and the goddess Artemis holding Daphne’s brother for ransom, upends her carefully laid plans. In return for her brother’s life, Daphne must find and return nine mysterious items stolen from Mount Olympus before the gods’ power wanes and the mortal world is thrown into chaos. Her journey leads her into battle with foes from ancient Greek myths, a growing (and dangerous) attraction to the enigmatic and flirtatious god Apollo, who has a secret agenda of his own, and into the devious games of the gods themselves.
