When the latest book in the Daring Do series is delayed, Rainbow Dash and her friends decide to offer their help to the book's author so that she can finish it. The writer does need help, but not in the ways they'd imagined.

Rainbow Dash attends the Daring Do Convention in Manehattan and meets a pony named Quibble Pants who despises Daring Do as much as she loves it. The two of them get wrapped up in a real life Daring Do adventure and must settle their differences if they have any chance of surviving the convention.

When Rainbow Dash’s favorite author, A.K. Yearling, announces her retirement, she convinces Pinkie Pie to go on a quest to find out if the Daring Do book series will be closed forever.

When a previously unheard-of author writes a novel trashing Daring Do, exposing her as a real pony, and praising Dr. Caballeron, Rainbow Dash rushes to defend her friend, while Fluttershy is more sympathetic to the "misunderstood" Caballeron.
