Ares thought they knew what love was when they obeyed Atreus Akti's
dying wish and slept under the sands of Arktos for centuries. But when
they awake at last, they find the world has changed. Arktos is on the
cusp of a civil war, but most of the Arkoudai no longer want their
patron deity to lead them into battle. Ares' family has grown, and
Ares is left adrift. And their former lover has been reborn into
Kataida Akti, who challenges Ares' concept of love itself.

As the daughter of the Strategos, Kataida Akti has always tried to be
a loyal soldier of Arktos - despite a restlessness and quiet longing
for combat that has plagued her for most of her life. When War comes
to Arktos, she's eager to prove herself and finally satisfy the
bloodlust that burns like a flame under her skin, but soon learns the
reality of this particular conflict involves far more than a cult who
seeks to take over Arktos. As Ares lends their sword and their
presence to the battle - and Kataida's bed - Kataida will have to
confront long-buried desires of her own, along with truths that will
shock Arktos to the core.

natural power exchange/biological kink imperative, and a love story
between a dominant, delightfully sadistic lady soldier and a
submissive, cheerfully masochistic god of war.)
