Mark Lawrence was born in Champagne-Urbanan, Illinois, to British parents but moved to the UK at the age of one. He went back to the US after taking a PhD in mathematics at Imperial College to work on a variety of research projects including the `Star Wars' missile defence programme. Returning to the UK, he has worked mainly on image processing and decision/reasoning theory. He says he never had any ambition to be a writer so was very surprised when a half-hearted attempt to find an agent turned into a global publishing deal overnight. His first trilogy, The Broken Empire, has been universally acclaimed as a ground-breaking work of fantasy. Mark is married, with four children, and lives in Bristol.
