Anticipation for Rebecca Yarros’ Onyx Storm is at an all-time high, but nearly a year after its release, Iron Flame‘s twist ending continues to perplex readers. While Yarros has dropped several teasers heading into the third book’s publication—including a three-page excerpt from Onyx Storm in Cosmopolitan UK—there are still several questions concerning Xaden turning venin. Xaden’s big reveal comes at the very end of Iron Flame, but when the story picks back up in Xaden’s end-of-book bonus chapter, Yarros skips ahead in the story’s timeline.
