The fourth title from the author-

artist Emily Rand explores environmental issues, recycling, and the importance of being neighborly

Mr. McDuff lives in a house full of stuff! He loves collecting things—bits and pieces that he thinks could be useful one day, but that his neighbors call junk! They all keep their houses neat and tidy, and hurry by without saying hello. Everyone except Mo, that is. Can Mo and Mr. McDuff convince the rest of the neighborhood that his stuff is useful, and that reusing and repairing is often better than throwing things away?
