The last chapter of LNDtH2 Part VIII: Becoming the Storm posts on Wednesday 16 March and with it the Intro to Part IX and the final Cast List. DON'T READ THE CAST LIST!
In order to give people a complete reference to look back on as they read, there is a lot of information in the cast list that doesn't get revealed until way late in the story. If you read the cast list up front, you will discover who is born, who dies, what casa are created, who marries whom, when, what new characters are introduced, and a ton of other information that you might not want before the actual chapter in which it is revealed. So, only use the cast list to look back at when you have a question about someone you don't remember. Also, go back to it and read it in June when the story ends and it will give you a nice summary of where everyone ends up at the end of the story.
There are 33 chapters in Part IX: Heaven's Gate. (Chapters 91-123) including the Epilogue. It will begin posting on March 16 (typically around 8:30 p.m. Eastern Daylight Saving Time) and will conclude on June 20. Chapters will return to posting every three days (not four days as the current part has). All chapters have been uploaded to SOL and are in the posting queue, so if I drop off the face of the earth while I'm traveling Europe and Asia, you still get the whole story.
