Every writer wants to create something that lasts. A book that sells. A story world where readers return again and again, across years, even generations. Little House on the Prairie. The Chronicles of Narnia. Harry Potter. And nearly 100 years after its first publication, Nancy Drew.

Even if it isn’t one’s goal to write a multi-book series, the principles behind Nancy Drew’s staying power apply across genres and formats for all writers to consider. Readers connect with characters they enjoy, understand, and trust.

Originally written for girls aged 12–16, Nancy Drew has expanded into more than 600 mysteries since its debut in 1930 and an IP world that now includes a series for even younger readers, one with college-era stories, a modern reboot, and a contemporary relaunch. Television, film, and video games have sustained a global readership spanning generations, and Nancy Drew is arguably the earliest and most enduring example of a scalable story world.
