’Tis the season for buying, giving, and donating books. Penguin Random House is embracing that spirit of generosity with the launch of #GiveaBook, a social media campaign that promotes books as holiday gifts, and also serves as an avenue to donate books to U.S. children in need via the aid organization Save the Children. Each time the hashtag #GiveaBook is used on Facebook and Twitter before December 25, Penguin Random House will donate a book to Save the Children, up to 25,000 times.
