The Liszts make lists. They make lists most usual and lists most unusual. They make lists in winter, spring, summer, and fall. They make lists every day except Sundays, which are listless. Mama Liszt, Papa Liszt, Winifred, Edward, Frederick, and Grandpa make lists all day long. So does their cat. Then one day a visitor arrives. He's not on anyone's list. Will the Liszts be able to make room on their lists for this new visitor? How will they handle something unexpected arising? Kyo Maclear's quirky, whimsical story, perfectly brought to life by the witty, stylish illustrations of Júlia Sardà, is a humorous and poignant celebration of spontaneity.
