All is fair in love and war. Renaldo has lived happily by that proverb his entire life. But he has finally met his match, and he's about to discover how unfair love and war can be.

When demigod and warlord Lord Renaldo takes a beautiful stranger captive during an ambush, he is delighted to have found a distraction that will keep him entertained during the upcoming siege. Little does he know, Casto is keeping more than just one secret from him. Slowly, Renaldo gets sucked into a turbulent roller-coaster relationship with his mysterious prisoner, one that begins with hatred and soon spirals into a whirlwind of conflicting emotions. And when it seems that things can get no worse, an old enemy stirs right in the heart of his home.

Determined to keep Casto by his side, Renaldo has to find a balance between the capricious young man and his own destiny as a ruler and god to his people.

Gods of War: Book III

In war, loss is the price of victory, and the cost of love is sometimes pain.

After Renaldo and Casto finally celebrate their marriage, the time has come for revenge against the followers of the Good Mother who tried to kill Casto—though this time, the gods of war won't use bloodshed to take Medelina. 

As a member of the Confederation of the Plains, Medelina answers to Ummana, the head of the alliance… and Casto is heir to the throne of Ummana. Accompanied by their most capable mercenaries, Canubis and Renaldo travel to Ummana to make Casto king.

They'll face the Council of Elders; Lord Aran, Casto's father; and Princess Anesha, Casto's sister—none of whom are happy about the king's return. For Casto, the city is a reminder of a terrible childhood, and Renaldo can only helplessly watch his beloved fight a seemingly hopeless battle.

Through trickery and political scheming, vengeance against the Good Mother is finally within their grasp—but their success might be bittersweet. Not everyone will return to the Valley with Casto and Renaldo.

Gods of War: Book IV

Though some struggles have ended in victory, ease and contentment are not the fate of the gods of war. Instead they must contemplate the sometimes terrible and frightening nature of their powers—and the effect those powers have on the people they love.

After their campaign in Ummana, the gods of war return to the Valley with their ranks finally complete. Sic is the eighth Emeris to join Renaldo and Canubis in their war against the Good Mother. Even so, they must wait for their powers to manifest, and trials lay ahead.

It is only when a tragedy befalls Aegid, Kalad, and Daran that Sic learns the extent of his abilities as a Luksari. What he achieves will change Daran forever—and set him up for trauma that leaves him doubting his relationship with Aegid and Kalad. After surviving battle, torture, and rape, Daran must affirm his commitment to his lovers and his new status among them through even more blood and violence.

Even though Renaldo and Casto's relationship has improved, they're still struggling, which could prove to be more dangerous than they think—because the Good Mother is already plotting her next move.
