Kace was worn out because of the side effects of the battle with the humans, so it was almost impossible to wake him up at this moment.
Thus, Hope thought of seeing Calleb later when the sun hit the horizon.
However, as she almost slip into a deep slumber, the howling pain, slowly but eventually stopped. As if the beast had finally calmed down...
Or, maybe it was only Hope's illusion?
The same thing was noticed by Lilac, she was also awaken by the sound of the sorrowful howling that rang through the silent night.
She forced herself to stay awake as she wanted to check what actually was going on, though she knew where that sound was coming from.
Calleb's beast was still mourning over the loss of his mate and since nothing could be done to bring Rossie back, they didn't know until when this would continue.
