Natalie Smillie grew up in Devon, England, and was not quite born with a pencil in her hand but pretty close! She’s done lots of things with her life so far including joining the Royal Air Force, moving to Scotland, and going back to college at twenty-seven. Natalie currently lives in northern Ireland with her husband, dog (Maggie), and an aloe vera plant named Kingston. She’s obsessed with toffee, tea, and carrot cake, and if she could be an item of clothing she would be a cardigan.
