Joseph Zigmond started as a HarperCollins graduate trainee in 2011, before joining William Collins as editorial assistant the following year. He has since gone on to acquire a range of non-fiction titles, including books by Bella Mackie, Microsoft c.e.o. Satya Nadella's, and Dunkirk by historian Joshua Levine, which he commissioned directly from the author and which was made into a Christopher Nolan film of the same name. He went on to work as senior commissioning editor for John Murray. Constance is his first book.
