Perfection Challenged

In the fourth novel in USA Today bestselling author Jade Kerrion's Double Helix series, the 'perfect human' Galahad finally challenges his imperfect genetic donor Danyael - and only one will live.

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.
