Imagine a 24-hour book sale that lasts for days and offers millions of titles at discounts of up to 95 percent off retail price. This was the stuff of fantasy for bibliophiles until 2009, the year that the Big Bad Wolf (BBW) Book Sale was born.

Read the backstory of BBW creator Andrew Yap, who shared that BBW was inspired by a personal story about an unfulfilled childhood need.
