The Wrath of a Gargoyle #romance alien

Continuation of Hybrid - the Apocalypse

And on the old apocalyptic Blue planet, now dominated by native and mutant creatures. He needed more than ever to ensure that the first female of the K'Aldriants did not have a chance to generate descendants with greater strength and adaptability.
Klaus just hadn't revealed yet that it was too late.
