Finicky

As Thanksgiving rolls around, Aldo Zelnick — a fifth-grade foodie if there ever was one — is flummoxed by his best friend Jack's refusal to try new food. Jack, who famously eats nothing but peanut butter sandwiches for lunch, is so finicky that he's even grown squeamish about Aldo's incessant talk about food.
Meanwhile, a family friend has opened a new restaurant, and Aldo, Jack, and Bee are invited for a kitchen tour and cooking lesson, and to help serve the homeless on Thanksgiving Day. With flash mobs, black-footed ferrets, a friend with a food allergy, and all the folderol this A-to-Z series is known for, this sixth installment also features a vocabulary-building glossary of fun and challenging words starting with the letter F, including fluke, and frenzy.
