M.G. Harris was born in Mexico City and grew up in Frankfurt, Germany and Manchester, England. As a teenager, during regular visits to her father in Mexico, M.G. became fascinated by Mayan archaeology. She made several trips to Mayan ruins in Yucatan and Chiapas and one such trip gave her the seed of the idea of what would later become The Joshua Files. M.G. was interested in molecular biology and studied biochemistry at St Catherine's College and St Cross College, Oxford University. M.G. spent several years working in research laboratories before setting up her own internet company. A skiing accident in 2004 forced M.G. to spend many weeks recuperating from surgery. She decided to keep a promise she'd made to herself to one day pursue a career as a novelist. Writing on a laptop next to her bed, M.G. began work on a techno thriller which combined her two intellectual loves - archaeology and biology. From this initial manuscript came the idea for a story featuring a young boy searching for a lost Mayan codex ... and 'The Joshua Files' were born.The first title in the series, 'Invisible City' was the UK's fastest-selling children's fiction debut for 2008.M.G. lives in Oxford with her husband and their two daughters.
