Night Season - Book 3 of the Keepers Series
The dragons rumbled low in their throats, they didn't like the void. "Listen!" Lady Thunderstroke said at last, standing near to her dragon some distance away, "There's a voice coming out of that thing!" The men concentrated on the strange opening and at last agreed, "You're right, but what a terrible voice!" "And they're speaking threats too!" "Someone is in harm's way inside that thing!" "I wonder where it goes, and how we can help them?" Lady Thunderstroke looked quietly up at her amethyst dragon and the dragon chirped. The Lady pulled her sword out and strode forward between the men and into the void saying "Only one way to find out - wait here!" and she was gone.
