Brown drew on true events from her family's history for this harrowing tale of love, loss, and everything in between.

"Inspired by my Nanny Ruth, this book is very personal and close to my heart. I grew up listening to stories about her time living through the war. I'm honored to keep her story alive," Brown said in a statement, per Deadline.

Nineteen Steps will hit bookstores on September 12.

Along with her first step into the world of writing, Brown has an impressive slate of upcoming projects across film and television.
