A love between a goddess and a mortal ignites a dangerous clash that could destroy both heaven and earth in this star-crossed enemies-to-lovers duology opener from Tiffany Wang. Perfect for fans of The Girl Who Fell Beneath the Sea and Six Crimson Cranes!

Ailan has many older sisters, but Xifei is the one she loves most—and the one she’s secretly betrayed. So when her sister vanishes from the Heavens, Ailan is willing to cross the entire mortal realm if only to bring her back, no matter the cost.

Kai despises immortals. Marked forever by the god who stole his brother’s life, he’s spent every day since chasing vengeance. They say immortals cannot be killed, he’s determined to prove them wrong.

When Ailan descends from the Heavens searching for her sister, Kai seizes his chance, offering to guide her to an oracle who might help, all while hiding a darker plan. But their journey through the Middle Kingdom pulls them into the deadly schemes of tyrants and demons. And as betrayal gives way to something far more dangerous, Ailan and Kai will have to decide what matters most—revenge, loyalty… or each other.
