Eidolon (Los reyes de las sombras)

Prince Brishen and his human wife, Ildiko, watch their world crumble as a demon horde ravages the Kai kingdom. As survivors seek refuge, Brishen faces unbearable pressure: he is pressured to renounce the woman he loves and marry a Kai to preserve the royal bloodline. Torn between love and duty, Ildiko fears becoming an obstacle to her people's future. Separated by war, death, and impossible choices, Brishen and Ildiko will discover that to love means to fight together, even when all seems lost.
