Adam Kay is a multi-award-winning writer, comedian and former doctor. His first book, an undergraduate textbook called Rapid Obstetrics and Gynaecology didn't do particularly well, but his next two did rather better. This is Going to Hurt has sold over two million copies, been translated into 37 languages, and is the bestselling narrative nonfiction title of the decade, spending over a year at number one in the Sunday Times bestseller chart. It is soon to be a major BBC comedy-drama. His follow-up, Twas the Nightshift Before Christmas, sold over 500,000 copies in the last three months of 2019, and saw him become the first author to have simultaneous Sunday Times number ones for both hardback and paperback nonfiction titles.
