Regina and her mom are busy preparing for her birthday party. It_s going to be a princess party with the perfect cake that looks like a castle and has ice cream cone towers. Regina is inviting all the girls in her class, including her best friend, Paula. Paula is excited, too, until she finds out about the cake. It will have nutty fudge brownies and peanut butter candies. Paula can_t eat that cake_she can_t go anywhere near that cake_because she has a peanut allergy. Regina thinks more about her friend and the cake until she comes up with a great plan that will please everyone.
