On International Women’s Day, many celebrities stepped out wearing red and shared inspirational messages of empowerment on social media. Emma Watson took her A Day Without a Woman action one step further.

The “Beauty and the Beast” star took on another role on Wednesday: "red-striking ninja book-fairy," as she called herself on Twitter. Donning a red beret, Watson hid books (written by women) near various statues and monuments of famous historical women in New York City.  

The actress posted videos of herself hiding books at the Gertrude Stein statue in Bryant Park, the Joan of Arc statue in Riverside Park and Harriet Tubman memorial on St. Nicholas Avenue, among others. She also hid a few outside Bluestockings, an East Village bookstore known for holding regular feminist-focused book clubs and events. It was there that Watson was spotted by a fan who recognized the former “Harry Potter” actress — but that didn’t blow her cover.

This isn’t the first time Watson has hidden books around the city. The actress posted videos of herself dropping books off at various subway stations on Nov. 9, 2016, one day after Trump won the 2016 presidential election.

According to The Book Fairies, a group of avid readers who hide books in various cities around the world, Watson hid “My Life on the Road” by Gloria Steinem, “The Color Purple” by Alice Walker, “Persepolis” by “Marjane Satrapi, “How to be a Woman” by Caitlin Moran, “Mom & Me & Mom” by Maya Angelou and “Half the Sky” by Sheryl WuDunn and Nicholas Kristof.
