According to Variety, the logline for the series is as follows: “In ‘Fourth Wing,’ Violet Sorrengail is forced by her mother to enter the brutal world of Basgiath War College. Based on the fantasy adventure from NYT bestselling author Rebecca Yarros, Violet joins hundreds of candidates striving to become the elite of Navarre: dragon riders.”

“Few stories have inspired the kind of passionate, worldwide fandom that Rebecca Yarros has built with Fourth Wing, and we know just how much Violet and Xaden mean to readers,” said Peter Friedlander, head of global television via Variety, Amazon MGM Studios, in a statement. “Esther and Emilio are rare and exceptional talents who bring something truly special to these iconic roles.”
