Heaven went to sleep ignoring the fact that the mark had faded away and that it probably meant something was wrong with Zamiel. But she would not care. He was a grown man, powerful and ancient. He didn't need her help; she tried to convince herself, and it didn't work.
She lay in bed turning back and forth, her mind filled with questions and her heart hammering loudly at the thought of what might have happened to Zamiel. Ancient demons might not be killed easily, but they could probably kill themselves.
Zamiel wouldn't do that. Would he?
What if she didn't do something soon and ended up regretting it for the rest of her life? This was a matter of someone's life. She shouldn't even be thinking and hurry to save him before it's too late.
