In addition to other writing, Marcus Ewert has worked on children's books since his teens, achieving acclaim with his award-winning books 10,000 Dresses (2008) and Mummy Cat (2015). 10,000 Dresses has been used in schools, churches, and youth groups around the world, as the first children's book featuring a transgender character. A hoarder himself, Marcus wrote his most recent book, Mr. Pack Rat Really Wants That, to puzzle out a resolution to his personal hoarding dilemma. Marcus lives in San Francisco, in a beautiful--and de-cluttered--apartment.
