The Perfectionists: 1

Sara Shepard is the author of the #1 New York Times bestselling Pretty Little Liars series. Her first story ever, which she both wrote and illustrated, was about friendly yellow creatures that lived in a backyard garden. It won second prize at the State College, Pennsylvania, library and was bound and placed on the shelf. Shepard and her sister, Alison, have been creating many joint creative projects for years-claymation movies, art installations, and video game designs-based on a world they made up when they were six and nine years old. They're pretty sure they're the only ones who find the world funny, though.
