Firebird is a science fiction romance by Kathy Tyers originally published in 1986, rewritten as Christian science fiction and republished in 1999. The second edition is part one of a three-part series, entitled Firebird: A Trilogy.
The protagonist is Lady Firebird Angelo, a wastling of the Naetai royal family. Wastlings are younger offspring of noble houses who are doomed to geis, or honorable suicide, so as not to upset the succession of their older siblings (and their children) to political power. Firebird disagrees with the actions of her government, but is compelled by honor to support it.
Firebird is the third daughter of the Queen of Naetai and a military pilot. Because she is a wastling, an unwanted heir to the throne, she is considered expendable. Leading her tagwing fighter group of wastlings on a suicide mission as part of a venture to capture a Federate world outpost, she is captured by Federate colonel Brennen Caldwell, a telepathic intelligence officer seeking to capture an enemy fighter for interrogation. She attempts honorable suicide by poison for her failure, but Caldwell thwarts her medically. Under telepathic duress, her military and political knowledge is used by Caldwell to save the Federate outpost. Firebird begins to see the dishonorable tactics of her mother's government for what they are.
Caldwell, in addition to being the most powerful Ehretan telepath of his generation, is the most senior telepath in a government that mistrusts them for their abilities. In addition to the government's mistrust of his people, Caldwell is questioned by his own people for his deep connection with Firebird. In her, he sensed a strong possibility of connaturality, a deep personality congruity that is essential for telepaths to have a successful relationship in marriage. Among his people there is a strong belief that, as the strongest telepath among them he should not marry outside his people, diluting the genes that allow their telepathy. Caldwell rejects his people's attitudes towards non Ehretans and continues his growing friendship with his prisoner, offering life and a future to one who believed herself as good as dead.
Following Netaia's failure on Veroh, the queen is forced to honorable suicide and Firebird's sister Carradee ascends the throne. Caldwell is assigned to Naetai as the Federate representative and brings Firebird with him. While Carradee favors a conciliatory posture with the Federacy, their other sister, Phoena, secretly plots the overthrow of Federate occupation along with members of the nobility, by secretly building an ecological weapon of great power. After several political and military dangers are overcome by Caldwell and Firebird, they ignore his orders and carry out a special ops mission to destroy Phoena's research lab.
