The mó — beautiful, ravenous demons who drink the souls of mortals — roam free and they will not cease until all the realms fall to darkness. Àn’y?ng must risk everything to stop them. But a betrayal has turned the tides of this war: her handsome rival from the Immortality Trials and the man she was falling in love with, Yù’chén, is now the enemy. Yù’chén is half mó — his mother is the Demon Queen of the Kingdom of Night, and the monster responsible for killing Àn’y?ng’s father. Àn’y?ng’s one hope is the boy in the jade — her lifelong guardian and heir to the last mortal Emperor — Hào’yáng. Together, they must join forces to rally an army that stretches across realms, from the Four Seas of the Dragons to the Phoenixes of the Golden Desert. But first Àn’y?ng must awaken the immortal power slumbering in her own veins… PRAISE FOR THE THREE REALMS DUOLOGY ‘A beautiful tale of duty, danger, and desire’ Rachel Gillig, Sunday Times bestselling author of One Dark Window ‘Simply gorgeous’ Nisha J.
