Marie wrote her first and most successful book, The Life Changing Magic of Tidying Up, in just three months as a way to help her clients, many of whom were on long waiting lists for consultations from the organizing guru, learn her methods. Since its 2011 release, the book has sold more than eight million copies around the world and spent countless weeks on bestseller lists, but there's more to read from the famous author. Spark Joy: An Illustrated Master Class on the Art of Organizing and Tidying Up was released in 2012 and The Life-Changing Manga of Tidying Up: A Magical Story in 2017.
Up next for Marie is Joy at Work: The Career-Changing Magic of Tidying Up, which will reportedly be published in 2020.
