Archangel's Lineage

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.
