The marriage pact between the elves of the west and the trolls of the north was an act of desperation. One the bride's mother, the dowager queen Ylva, despises herself for agreeing to. With a heavy heart she travels with the new elf king to deliver her only child to the halls of the mountain king. The troll prince, Torsten, however decides he does not want Ulf's daughter for his bride but Ulf's widow instead. In order to save her daughter, she gladly accepts and begins a tumultuous marriage with her sworn enemy that wakens her to things she did not know about the trolls, the elves or herself. When a disaster devastates the troll kingdom Ylva's loyalties will be tested. It will be up to her to decide if she wishes to use her connections and power to help them find a new home among their sister clan across the Windrose Sea or follow the path of vengeance and let the trolls die out.
