Meredith Walker began her career in journalism at the groundbreaking Nickelodeon series Nick News. She worked her way up from production assistant to segment producer, traveling the country to interview kids, experts, politicians, and artists for news stories. She later moved to Saturday Night Live, where she ran the talent department, before she and Amy Poehler cofounded Smart Girls, an online community that encourages young women to celebrate who they are and who they are becoming. 

Through programs, workshops, and day camps, Meredith has helped girls try new things and discover more about themselves. That work has taken her from classrooms and regional programs to the White House, the United Nations, and communities around the world. She now lives in Austin, Texas, with her longtime love, Tom, and their dogs Banjo and Farris. 

Nina Cosford has illustrated more than twenty books. She lives in the United Kingdom.
