Archangel's Lineage by Nalini Singh

New York Times bestselling author Nalini Singh’s dangerous and beautiful world of archangels, vampires, and mortals has never faced a threat this cataclysmic…

Raphael and Elena are experiencing their first ever year of true peace. No war. No horrors of archangelic power. No nightmares given flesh. Until…the earth beneath the Refuge begins to tremble, endangering not only angelkind’s precious and fragile young, but the very place that has held their most innocent safe for eons.

Amid the chaos, Elena’s father suffers a violent heart attack that threatens to extinguish their last chance to heal the bonds between them and make sense of the ruins of their agonizing shared history.
