Dragon's Eye (Sumeria's Sons 5)

In the wake of birth and betrayal, Ushna takes the God Ashur to Tristan in a last desperate bid to save Tristan's life—and is helpless to do anything but watch as Ashur instead buries him in a grave. Though he has no desire to go on living, having now lost Brian and Tristan, Ushna has no choice. Not only do their children need him, the mysterious Simurgh has come out of hiding and forces him to continue on—for there is much to do and little time to do it, especially with treachery and danger closing in on them from every side.
