Kingdom of the Elf Lords

Kingdom of the Elf Lords is a four-book romantasy series by Heidi Vanlandingham, set in the Nine Worlds and picking up where Flight of the Night Witches leaves off. Elfkind has nearly vanished since the Great War, and two co-regents are left to find their people and rebuild Alfheimr. Each book gives a different couple a love worth fighting for: a Resistance soldier and the Huldra who defied her nature for him, a cursed elf and the queen of the dead, a healer with a buried secret and the death queen's daughter. Read in order, the books follow the search for the council of Elf Lords, and what it costs to bring them home.
