Pharrell gives us another reason to smile (it’s the perfect day for it.) The power producer joined forces with a publishing house and literacy nonprofit–FirstBook–to help donate 50,000 books to young book worms from low-income homes.

Penguin Young Readers christened the partnership by unveiling new hastag #readHappy. Where kids can tweet why reading makes them “happy.”

“Every child on this planet deserves to experience the joy of reading,” Pharrell said in a statement.

He has a few of those cuties in his book trailer.

You can pick up a copy of “Happy!” on October 6th.
