When the Katz family moves in, C.J. the mouse is scared. Nibbling jelly doughnut crumbs in the kitchen, he hears a soft voice say, "Hello." The Katz family is spinning a dreidel and eating chocolate coins. It looks like fun, but a mouse can''t play with cats! "Hello again," says the soft voice. "Please don''t go. I could use a friend." Can C.J. overcome his fear and make some new friends just in time for Hanukkah?
