In the world of the goblins, there is only one rule...Khemael, called both Angel and Demon by the superstitious humans, is a creature of beauty and grace, with a mostly human appearance. His love of stretching his leather-like wings and flying freely in the world of men brings far too much attention to the existence of the goblins. Haghuf, with the old ways entrenched into the very core of his being, knows that the inevitable responsibility will fall to him. He must destroy the beautiful creature who, in the world of the humans, would be called his grandson. Amidst unrest among the more fearful humans south of the river and disparity in the world of the goblins, messages come from Anton who travels in the north. A different kind of invader than those they have encountered before moves towards the city. They are moving south. Whatever happens, the impending incursion will bring change to their world...and Khemael's flights threaten to bring the danger to the goblins.
