H.S. Z.M. 1D. When America's Sweetheart, Ludmilla Hanson, is admitted into rehab, she asks her identical twin sister, Camilla, for a favor. She needs Cami to take her place during the shootings of a new major movie. Normally, it wouldn't be a problem for Cami—she's used to do everything her sister wants—except this is THE Movie of the year, featuring none other than Harry Styles—and he kinda makes her jittery. Follow Cami, Harry and Zayn on Set as they deal with acting, singing and crazy fans. ____________ Excerpt: Harry grabbed my arm, stopping my escape.

His dark curls covered his eyes, and I couldn’t see him properly. Was he mad? It felt like he was mad—the grip on my arm was tight. “Answer me,” he shouted.
