For those who haven't finished reading \"Onyx Storm,\" warning -- spoilers ahead!

Yarros was also asked if she has a message for fans to give them hope and mend broken hearts after the novel's dramatic conclusion.

\"It's a five book series -- just hold on,\" she responded.

On the book's final scene and its last line, she reflected, \"Before I start a book, I know its first line and its last line and that last line had been in my head since I wrote the synopsis for 'Fourth Wing.'\"

\"So it was really, really satisfying to finally get there and get all those emotions out,\" she continued.

@gma “We really gotta drag them down to the depths so they can arm up and fight.” Brace yourself, @Rebecca Yarros fans, because she says things are “probably” going to get reaaaal bad in her next book. #onyxstorm #rebeccayarros #fourthwing #ironflame #bookstagram #romantasy #gmabookclub #booktok ♬ original sound - Good Morning America

When asked what she can tease about the highly anticipated upcoming fourth novel in the series, Yarros shared, \"I can tell you there will be dragons and politics. Maybe some romance, maybe some intrigue -- but definitely dragons!\"

Yarros also shared her excitement for the upcoming \"Fourth Wing\" TV adaptation and praised its showrunner, Moira Walley-Beckett.

\"I can tell you that I've read the pilot and it's incredible,\" she said. \"Moira Walley-Beckett is phenomenal and just so talented and gifted, and she really captured the spirit of the book and the characters. My only non-negotiable is that Xaden isn't white.\"
