Stacy McAnulty doesn't think the world will end suddenly, but she does worry about the ongoing damage to the environment caused by her species. Nonetheless, she believes Homo sapiens can overcome challenges and reverse course by taking action. Before becoming an author, Stacy was a mechanical engineer (and before that-like in fourth grade-she was an aspiring astronaut). Her love of math and science is reflected in most of her books. She writes chapter books, middle-grade novels, including The Miscalculations of Lightning Girl, and picture books, including the Our Universe series, which explores space and the natural world. Save the People is her debut middle-grade nonfiction. Originally from New York, she now lives in North Carolina with her family.
