Fourth Wing by Rebecca Yarros

࣪ ִֶָ☾. The story follows Violet Sorrengail, a young woman who was supposed to live a quiet life as a scribe among books. However, her mother—the commanding general—forces her into the brutal Riders Quadrant to compete for a chance to bond with a dragon.
Violet is physically fragile, making her an easy target in a world where dragons incinerate "weak" humans. She faces hostility from cadets who want to improve their own chances and from Xaden Riorson, the powerful and ruthless wingleader whose father was executed by Violet's mother.
Amidst the deadly training and political intrigue, Violet must rely on her wits to survive. She discovers that the war is more dangerous than leadership admits, and a terrible secret threatens the kingdom.
