Between now and February 15, US McDonald’s will be giving away books in their Happy Meals!

In Partnership with Reading is Fundamental, the fast food chain will switch out the meal’s typical toys for one of five miniature-size paperback books. Sticking to a Valentine’s Day theme, the books include Happy Valentine’s Day, Mouse! Pete the Cat: Valentine’s Day is Cool, Clark the shark takes heart, as well as Michael Bond’s beloved A Bear called Paddington.

The combination of books and burgers is not a novel one. The fast food giant began distributing books in 2013, including a special giveaway in the UK last winter, when 14 million Roald Dahl books were included in Happy Meals.

According to McDonald’s, by the end of this year, it will have distributed more than 50 million books to children in the US — enough to provide a book to every child under the age of 12.
