Andrew Grant was born in Birmingham, England in May 1968. He went to school in St Albans, Hertfordshire and later attended the University of Sheffield where he studied English Literature and Drama. After graduation Andrew set up and ran a small independent theatre company which showcased a range of original material to local, regional and national audiences. Following a critically successful but financially challenging appearance at the Edinburgh Fringe Festival Andrew moved into the telecommunications industry as a ‘temporary’ solution to a short-term cash crisis. Fifteen years later, after carrying out a variety of roles – including a number which were covered by the UK Official Secrets Act – Andrew escaped from corporate life, and established himself as the author of the critically-acclaimed novels Even, Die Twice, More Harm Than Good, RUN, False Positive, False Friend, False Witness, Invisible, and Too Close To Home. Andrew is married to novelist Tasha Alexander, and lives on a wildlife preserve in Wyoming, USA.

Lee Child was born October 29th, 1954 in Coventry, England, but spent his formative years in the nearby city of Birmingham. By coincidence he won a scholarship to the same high school that JRR Tolkien had attended. He went to law school in Sheffield, England, and after part-time work in the theater he joined Granada Television in Manchester for what turned out to be an eighteen-year career as a presentation director during British TV's "golden age." During his tenure his company made Brideshead Revisited, The Jewel in the Crown, Prime Suspect, and Cracker. But he was fired in 1995 at the age of 40 as a result of corporate restructuring. Always a voracious reader, he decided to see an opportunity where others might have seen a crisis and bought six dollars' worth of paper and pencils and sat down to write a book, Killing Floor, the first in the Jack Reacher series.
