Rebecca Yarros Posts About Book 4

Well it is official everyone. The fourth book in the Empyrean Series is in the works of being worked on. On March 19, 2026 she posted a video of herself writing #4 on a whiteboard and walking away. We don’t have a lot of infomation (RY doesn’t give much information in her interviews) but we do know that we will have multiple POVs and we will find out the “brother” that became venin at the end of book 3. She told us to pay attention to who was missing at the end. I am interested in hearing everyone’s opinions and fan theories on who they believe that is!
