Beth McMullen is an American author who writes spy-themed fiction for both adults and younger readers. Her first published series, Sally Sin, launched in 2011 with novels about a former CIA operative trying to balance motherhood in suburban San Francisco with her espionage past. The books mix humor with action in the vein of light spy thrillers.

McMullen later turned to middle-grade fiction with Mrs. Smith’s Spy School for Girls, a three-book series about a girl who discovers her boarding school is actually a training ground for spies. She followed that with the Lola Benko, Treasure Hunter series and the standalone Secret of the Storm. Her middle-grade novels share a sense of fun and fast pacing, with young protagonists who are resourceful, brave, and often in over their heads.
