Ummana Volume 3 by Xenia Melzer
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.
