The biggest book sale in the world is coming back to Manila.

Big Bad Wolf made the announcement this Friday, promising, as with last year's first-ever edition, more than 2 million titles to be offered at a massive discount for Filipino book lovers.

The 2019 sale is scheduled to run from February 22 to March 4 at the World Trade Center in Pasay City.

Admission is still free and it will be open 24 hours a day.

Big Bad Wolf is the brainchild of BookXcess heads Andrew Yap and Jacqueline Ng, whose sole mission is to help introduce books to readers who normally couldn't afford one.
