A Covenant of Justice

In A Covenant of Justice, the sequel to Gerrold's classic space opera Under the Eye of God, The Phaestor, a genetically altered vampiric race, have set in motion their final plan for the complete enslavement of the galaxy. However, they will not go unopposed, for on numerous worlds, humans, androids, and bioforms have joined forces against their vampiric overlords.
A government of vampires, dragons, and mutated humans display their galactic dominance, and while those entrusted with the wisdom of the galaxy sanction the struggle against the Phaestor, a cunning Vampire war queen, her ambitious suitor, and the fierce and invincible Dragon Lord vie for total domination.
The last hope for the galaxy remains in the hands of rebels from Thoska-Roole: a band of malcontents, outnumbered and pursued, fighting for their freedom, their lives, and the future of the stars.
