[…] a Sidhe looked up at Aurilia and the thin voice whined, "But if the iron and silver that the Sidhe of the Bright Court set in Alhambra are removed, they will know someone has been there."

And then I started hearing rumours from the Courts—that when any Sidhe dies, they're no longer reborn." "Seriously?" I hadn't known how the Sidhe lived forever. […]"
2017, Emma L. Adams, Mortal Heir
