Lord of the Falconstar. Falconstar Trilogy, #3

To save his clan, Lord Khasan Valdamar must conquer his own broken house. The Valdamar Clan is on the edge of ruin. Its allies are wavering, its enemies are closing in, and the heir to Khasan's legacy is in the hands of the Tatari, his most dangerous rivals. Worse still, the women at the heart of his clan are divided by jealousy, betrayal, and old wounds that no Hameji warlord would ever think to heal.
Zenoba, once Queen of the Falconstar, has been cast down by scandal and estranged from the husband she fought so hard to claim. Tsarnai, Khasan's newest bride, finds herself abandoned by her birth clan and forced to carve out a place among sister-wives who see her as a threat. And Sonya-the captive who betrayed them all-is carrying Khasan's heir, caught between the enemies who stole her and the clan she may never be able to rejoin.
Every law of Hameji honor demands vengeance. Every instinct tells Khasan to harden his heart. But if Clan Valdamar is to survive, he must do the unthinkable: forgive the women who betrayed him, trust the ones who challenge him, and forge his fractured household into a weapon stronger than any war fleet. Because the Tatari are coming. And only a house united can raise the Lord of the Falconstar to his destiny.
