Seraphina, a supreme seraph, was betrayed and killed by her fiancé and adopted sister. Reborn, she bargains with Azriel, the ancient war angel trapped in the abyss, conceiving nine dark-winged cocoons in one pregnancy. When the nine offspring finally hatch, the Holy Court of the Firmament is stricken with dread—they nearly eradicated the nine supreme legion commanders of the primordial angels.
