Alone for a millennium, since a human murdered her beloved consort, Ashra, the immortal icrathari queen, rules over Aeternae Noctis, the domed city of eternal night. Her loneliness appears to be at an end when her consort's soul is reborn in a human, Jaden Hunter, but their reunion will not be easy. Icrathari are born, not made. If Ashra infuses Jaden with her immortal blood, he will be a vampire, a lesser creature of the night, a blood-drinker rather than a soul-drinker. Furthermore, Jaden is sworn to protect his half-sister, five-year-old Khiarra. She is the child of prophecy, destined to end the eternal night and the dominion of the Night Terrors-the icrathari and the vampires. As Ashra struggles to sustain her crumbling kingdom in the face of enemies without and treachery within, Jaden fights to defend his sister and unravel a greater mystery: what is the city of eternal night, and how did it come to be?

An alpha empath, Danyael Sabre has survived abominations and super soldiers, terrorists and assassins, but he cannot survive his failing body. He wants only to live out his final days in peace, but life and the woman he loves, the assassin Zara Itani, have other plans for him. Galahad, the perfect human being created by Pioneer Labs, is branded an international threat, and Danyael is appointed his jury, judge, and executioner. Danyael alone believes that Galahad can be the salvation that the world needs, but is the empath blinded by the fact that Galahad shares his genes, and the hope that there is something of him in Galahad? In a desperate race against time and his own dying body, Danyael struggles to find fragments of good in the perfect human being, and comes to the wrenching realization that his greatest battle will be a battle for the heart of the man who hates him.

Don't fear the army of genetically engineered perfect killers. Fear the cripple who leads them.
An alpha empath, Danyael Sabre is powerful, rare, and coveted, even among the alpha mutants who dominate the Genetic Revolution. Betrayed by his friends and abandoned to a life sentence in a maximum-security prison, Danyael receives freedom and sanctuary from an unlikely quarter-the Mutant Assault Group, an elite mutant task force within the US military. Physically crippled and emotionally vulnerable, Danyael succumbs to the warmth of friendships and the promise of love he finds within their ranks.
Friendship and love, however, demand his loyalty, and Danyael rises to the challenge of training and leading the assault group's genetically modified super soldier army. The super soldiers are faster and stronger than the military's human soldiers; their animal instincts spur ferocity and fearlessness in battle. Who is the perfect weapon, though, the super soldiers or Danyael, the alpha empath, who can, with a touch, heal or kill?
Adversaries swarm like vultures around carrion; the pawn is once again in play. The threads of betrayal that sent Danyael to prison spin into a web, ensnaring him. When a terrorist group strikes Washington, D.C., how far will Danyael go to defend a government that sent him to prison to die?
