Now that third-grader Aven Green has retired from sleuthing, it's time to conquer a whole new world: baking!Aven knows she is an expert baker of cakes and cookies since she has been baking with her mom for a really long time. Plus no one bakes quite like she does. She cracks eggs and measures sugar and flour with her feet--plus measuring cups--since she was born without arms.And now Aven has her eye on the prize: a beautiful blue ribbon for baking at the county fair. So she teams up with her friends Kayla, Emily, and Sujata. But it turns out they all have very different tastes and a lot of opinions about baking. Talk about a recipe for disaster!
