Autumn Cornwell is known for her adventurous and comedic style in Young Adult literature. Her global experiences, including encounters with squat toilets, jumbo centipedes, and ear nibbling, have inspired her works. She debuted with the YA comedic adventure, Carpe Diem, published in the U.S. by Macmillan and available in Germany, the Netherlands, and China. The novel narrates the journey of Vassar Spore, an overachiever who backpacks through Malaysia, Cambodia, and Laos with her bohemian grandma, experiencing a series of misadventures.

Her work with refugees and persecuted minority groups in Southeast Asia inspired her latest YA adventure, Never Sorry Ever. Cornwell's vivid storytelling is a testament to her own adventurous life and the real-life events she has encountered.
