Lexie Elliott was born and grew up in Scotland, at the foot of the Highlands. Her first attempt at a book came in primary school, and featured a horse; sadly, that manuscript has been lost. She attended a local state high school, Dunblane High School, and spent much of her teenaged years reading and swimming. In 1994 she began a Physics degree at University College, Oxford, where she obtained a first; she subsequently obtained a doctorate in Theoretical Physics, also from Oxford University. A keen sportwoman, she represented Oxford University every one of her seven years there in either Swimming or Waterpolo, and usually both. However, she never lost her longheld desire to become a writer and always had a drawer full of private scribblings.

After university, Lexie succumbed to the need to climb out of debt and find a job and began work for an investment bank in London, where she remained for 8 years. During that time she also took up triathlon, met her husband (in a swimming pool at 5.30am, but that is another story...), got married and had two gorgeous boys, swam the English Channel solo, ran a few marathons and ultramarathons and tried in vain to carve out enough time to write. After losing her banking job during the Global Financial Crisis, she began work part-time in fund management in the City of London, where she still works now; the rest of her time is spent writing, or thinking about writing, and juggling family life and sport.
