Starbucks has chosen Erin Morgenstern‘s The Night Circus as its first digital book Pick of the Week. The debut novel began as a National Novel Writing Month manuscript and endured 30 rejections from literary agents.

Last summer, The Wall Street Journal explored Morgenstern’s “high-six-figure advance” and her potential as a successor to J.K. Rowling in an article, but we uncovered some practical advice for aspiring authors.

Here’s more from the WSJ: “In 2005, [Morgenstern] crashed out a manuscript during National Novel Writing Month … Very little from that early draft survived, but she had an idea that excited her. She worked in bursts over the next several years, writing a sprawling, plotless series of vignettes featuring magicians, acrobats, and a pair of psychic twins. Thirty literary agents rejected her.”

Writers can learn two important lessons from this story. Your National Novel Writing Month (NaNoWriMo) manuscript is only a first draft and needs months or years of editing before publication. Most importantly, don’t give up–keep trying to find an agent who loves your kind of story.

Correction: An earlier version of this post erroneously identified the book as Starbuck’s first digital pick.
