The Huntresses of Artemis must obey two rules: never disobey the goddess, and never fall in love. After being rescued from a harrowing life as an Oracle of Delphi, Kahina is glad to be a part of the Hunt; living among a group of female warriors gives her a chance to reclaim her strength. But when a routine mission goes awry, Kahina breaks the first rule in order to save the legendary huntress Atalanta.
To earn back Artemis's favor, Kahina must complete a dangerous task in the kingdom of Arkadia-where the king's daughter is revealed to be none other than Atalanta. Still reeling from her disastrous quest and her father's insistence on marriage, Atalanta isn't sure what to make of Kahina.
As her connection to Atalanta deepens, Kahina finds herself in danger of breaking Artemis's second rule. She helps Atalanta devise a dangerous game to avoid marriage, and word spreads throughout Greece, attracting suitors to go up against Atalanta in a race for her hand. But when the men responsible for both the girls' dark pasts arrive, the game turns deadly.

Still, with her sister's life in the balance, Lena is willing to risk it all. She's willing to kill. How far will she go before the darkness consumes her?
