Megan Hirsch has written “I will not chew gum at school” (500 times), law school exams (not very well), messages on dirty windshields, intentionally tricky test-prep math problems (sorry), recipes for vegan lemon bars, landscaping plant lists, high school course descriptions, parking ticket appeals, grants for bicycle lanes, and now picture book manuscripts. She hails from an herb garden in Los Angeles with a cat she buys food for but doesn’t own.
