Who knows if you've been naughty or nice? Santa knows, that's who! But not everyone believes in Santa Claus. Bah, humbug. Consider Alfie F. Snorklepuss. He thinks he's proven that Santa Claus doesn't exist. Alfie thinks there is no way that Santa could do all the things he's supposed to, like deliver billions of presents all over the world in one night or know what every little kid wants. When Alfie starts spreading the word that there is no Santa Claus, he makes someone very unhappy: his little sister Noelle. And so Noelle turns to the only person who can help her. The one person Alfie thinks doesn't exist: Santa Claus. Ho, ho, ho! In this sweet and funny picture book from husband-wife team Cynthia and Greg Leitich Smith, with illustrations by Steve Björkman, Alfie gets an attitude adjustment, North Pole-style, from Santa and his elves, and Noelle gets exactly what she wanted for Christmas: a nicer big brother. - from Amzon
