All Monsters Must Fall Now that Hú Dié has escaped her glass cage, she craves revenge against her captor more than anything else. But her human half also covets the creature comforts she’s never had. As a butterfly fairy, Hú Dié knows she needs a lot of training before she can face the monster who kept her. Pretty man, Shén Mì meets all her needs—if she agrees to spy on the empress for him. But what does a man with such shallow interests want with the imperial family? Can he be harboring secrets and hiding behind a lie? Must Hú Dié seek revenge on her own? Or can she trust Shén Mì? Either way, she risks losing her freedom—and her heart.
