To escape the heat of the city, Kamala Khan and her friend Nakia visit a local museum's hallowed, air-conditioned halls. Unfortunately, it ends up being less of a refuge as the girls are blocked at every turn by sticky-fingered campers. But when one of the kids accidentally releases a jinn trapped in an ancient Mesopotamian exhibit, it’s up to Ms. Marvel to contain it before it possesses a camper and escapes into the streets of New York City to wreak havoc!
