Queens of Glass, Stone & Iron - Tommy L Barton - Bog

Three queens. Three kingdoms. One queen must defend against powerful invaders. Another must find a way to end the political strife within her borders. The last queen sits in her dark temple, breeding a monster, and must be stopped at any cost. An unlikely group of heroes must fight to defend the innocent people caught in the middle. Will the heroes prevail? Can any of the three queens survive and hold onto their rule?
