Firebreak. Firebird Interlude Trilogy, #1

What would you sacrifice to save your family and your home world?Lady Firebird Caldwell returns to the world of her birth, Netaia, intending to introduce her young sons to the noble Electors while her husband, Brennen, conducts a military inspection. When mysterious ships in distress suddenly approach the planet, the Electorate sends her to initiate first contact. Forced to work alongside a vengeful childhood enemy, Firebird uses everything within her power-even her passion for music-to negotiate, only to discover their alien technology threatens all the worlds she holds dear.
Facing ruthless betrayal, Firebird undertakes a deadly journey to salvage the mission. Brennen must make daring use of his telepathic powers to save human life in the galactic Whorl, including that of their young sons. But saving the worlds might force Brennen to give the order that would mean Firebird's death. In a galaxy poised on the edge of ruin, survival may demand the ultimate sacrifice-from them both.
