Tucker, The Cricket in Times Square, by George SeldenRead about another rodent on the list.
Tucker is a city mouse and a good friend to a musically gifted cricket named Chester. I loved this book when I was a kid. And I love this quote from George Selden about how the book came to be: "One night I was coming home on the subway, and I did hear a cricket chirp in Times Square. The story formed in my mind within minutes. An author is very thankful for minutes like those, although they happen all too infrequently."
