The Red Queen — Meg Xuemei X.

Some love dies. Some never does. After Forbidden Glory brings Lucienne back from death's door, she wanders between sanity and insanity. And instead of killing each other, Ashburn and Prince Vladimir must put their differences aside to save her. But one of them has to make a sacrifice. As the nation of Sphinxes is born, the Sealers rise again. When their multinational army arrives at Sphinxes' door with an ancient weapon that instantly sets Sphinxes ablaze, Lucienne summons Forbidden Glory one last time to protect her people from extinction.
