Long ago, Lord Stark Tower - the famed Witchbreaker - nearly wiped out the witches. Today, only a handful of women still practice the weaving craft in secret. The witch Sorrow, Infidel's fellow adventurer, has vowed to right this wrong, crushing the Church of the Book and launching a new golden age of witchcraft. In pursuit of her goal, she has bonded her soul with Rott, the primal dragon of decay, giving her near-limitless powers of destruction.

Unfortunately, this power has cost Sorrow her humanity, leading her to a desperate quest to find the greatest witch of all time, Avaris - rumoured to still be alive after hundreds of years - in hopes of mastering her dark magic before it destroys her. But she's not alone in hunting Avaris, as fate throws her into an uneasy partnership with a man who wants to be the new Witchbreaker. Can either of them survive their mutual quests when their journey leads them into battle with Tempest, the primal dragon of storms?
