Instead, Noah, the Academy Principal and a fallen Angel, swaps bodies with Kaleth, choosing to die on the guillotine in his place. Now, Kaleth must live in the shadows. He has a new identity, a world that hates him, and one final mission left behind by the angel who saved him: “Teach her how to be happy.
