Julia Cordover, president of the senior class at Marjory Stoneman Douglas High School, is planning a prom.

Cordover, 18, started working on the details last fall, overseeing the team of students that picked a date, booked a venue and found a DJ.

But she never could have imagined the challenge she faces now: figuring out how to memorialize four of her classmates, who died on Feb. 14 in the worst high school shooting in U.S. history. While the senior class prom will go on as planned in early May at The Westin Fort Lauderdale Beach Resort, the music and dancing will be punctuated by moments of silence that reflect just how much the Parkland, Florida high school has lost.

“It’s definitely been a different new normal,” Cordover said. “It takes a piece of our heart and it’s not the same.”
