France, 1348. The plague ravages the kingdom and the Inquisition is everywhere. Amicia and her younger brother Hugo are hunted through devastated villages, bound by a connection they barely understand. Their struggle to survive is only the beginning — and innocence does not last long. Then, after escaping their ruined homeland, the siblings travel south to new cities and new possibilities, hoping to start fresh and finally control Hugo's curse. When his powers awaken again and a flood of devouring rats returns, they are forced to flee once more — following a prophesied island that may be their only hope.
