Emma Watson has been promoting her book club 'Our Shared Shelf' in the best way – by hiding novels around the London Underground for people to find!
The Harry Potter star placed 100 copies of Mom & Me & Mom by Maya Angelou around tube stations across the city and left a note in each book, explaining why she had left a copy there.

One lucky commuter who found one of the novels shared the star's note on Twitter, in which Emma had written: "You are the finder of Our Shared Shelf's monthly book choice. Each pick is made with careful love and attention – we hope you like it.
"Just one hundred copies were hidden on the tube… Take special care of it and when you are finished please leave it on the tube again for someone else to find."
Books on the Underground - a group that leave novels on the tube for book lovers to find - worked with Emma on the project, and shared a snap of the actress hiding one of the copies, writing: "We were delighted that @EmWatson became a #BookFairy for the day to share copies of the next #OurSharedShelf read!"
They then posted a video of someone who noticed a copy on the escalator and picked it up during their journey.
"This was not a set up," they excitedly tweeted. "Great when someone sees a book & instantly grabs it! Hope you enjoy! Love from us & @EmWatson."
Book lovers were quick to join in on the fun, with many revealing that they had travelled the tube in the hopes of finding one of the copies. One tweeted: "I should be revising but I just have to go on a book hunt for @BooksUndergrnd."
"I lost a brand new book today but my Fairy Book Mother took pity and sent this to me on the central line train #booksontheunderground," another added.
