The Liszt family loves to make lists. They make lists of the most usual things and lists of the most unusual things. They make lists during winter, spring, summer, and fall. In fact, they make lists every single day of the week except for Sundays, which are entirely listless. Mama, Papa, Winifred, Edward, Frederick, and Grandpa spend their entire day cataloging the world around them. Even their family cat gets in on the list making action. But their perfectly organized routine is interrupted when a strange visitor suddenly arrives at their door. This mysterious guest is not on anyone's list at all. Will the family be able to make room in their tidy lives for something entirely unexpected? This whimsical story is a humorous and unforgettable celebration of spontaneity and keeping an open mind.
