During the invasion of New York in The Avengers, when Loki commands a crowd to kneel, the last person Tony Stark expects to obey is his own older sister. Intrigued by the sarcastic Stark woman who isn’t afraid of him—and may even find him attractive—the God of Mischief takes a particular interest in her. As Tony desperately tries to keep them apart, what starts as a ridiculous moment turns into a chaotic, romance between a Stark and the enemy.
