After Brandon's marathon writing session at the end of 2019, where he wrote 19k words in a single day, Brandon has confirmed via a reddit update that the first draft of Stormlight 4 is complete. Although Brandon still has four other drafts to do between now and July 1st, this marks a major milestone in the writing of this book. While Venli is the focus character for this book and has many viewpoints, it will be more of an ensemble than the previous Stormlight books.
Brandon is also hoping to write a novella over the next few months during the beta read and has said that it would be potentially focused on Rysn, Aimia, and the Sleepless. Because of this, he has yet to write the Rysn interlude for the fourth book, though we can expect to get one.
The Rock story that Brandon has previously said needed to be done before Stormlight 4, has seemingly gotten pushed back, as thematically his story did not fit with the rest of the book. If it’s not a novella between books four and five, however, we are likely to see it fit into the final book of the series.
While November 17th is still a ways off, the progress being made on Rhythms of War is both real and exciting to see.
