She came for funnel cake. She left a crater.

It's 1964, and the World's Fair is the pride of a shiny new future. Rocket rides, dancing robots, and fried everything. But when a strange cosmic flare hits the fairgrounds, one woman grows to impossible size, and her temper grows right along with her.

Suddenly, the crowd isn't watching the show. They're running from it.

As chaos erupts across the city, a washed-up beat reporter, a science dropout with a crush, and a terrified ex-boyfriend must team up to stop the towering force of nature in a polka-dot bikini. Can anyone survive the day when the biggest attraction becomes the biggest threat?

Awild ride of vintage sci-fi mayhem, atomic age weirdness, and giant-sized fun. She's tall, she's mad, and she's not done growing.
