Survival: a pretty word painting heroic pictures of larger than life deeds. But the act of survival is messy, cruel, brutal and unfair in every bruising shade, and it's something Ria Erfinder knows intimately. Since fleeing the London fires under the cover of darkness, Ria and her family have fought to remain anonymous. To remain hidden and do as they're told. That's how Witches in the era of the Hunts survive, so when tasked by her twin sister to find the last remaining Haven City, Ria will risk it all in the name of survival and freedom. But neither she nor her twin could anticipate the cost being so high. Driven off course by weather and wolves, Ria finds herself trapped as an interloper in a world far beyond her understanding. It will take every scrap of determination to make it out of Tree Spring alive, but while one twin struggles against the brutality of the Fae, the other will watch the shadow of the Huntsmen march into her town and head straight for her.
