" I’ve heard about the palace windows,” Rhema says. “One of the cooks told me that she worked in the kitchens there as a girl. She said that in the great hall of Violla Ruza, some of the windows have actual colored glass. Can you believe it? And there’s a rose on each one, with three circles around them.”
She was talking about the Renovian royal seal. Cal knew it well.
“The three circles symbol eternity. "
