Chester and Wilson have their own way of doing things, and they do everything together. When they cut their sandwiches, it is always diagonally. When they ride their bikes, they always use hand signals. If Chester is hungry, Wilson is hungry, too. They are two of a kind, and that's the way they like it--until indomitable Lilly, who has "her" own way of doing things, moves into the neighborhood. Full color. Paperback.
