Emma wants the Muses to help rescue her teacher, Mrs. Krishnamurti, from the evil (and rather doughy) clutches of her wicked foster father, Mr. Drinkwater. A helpful Muse, Feather would normally love to lend a wing. Unfortunately, Emma has arrived during the Great Pie War, a time when any sudden moves could result in getting a smart pie full in the face. You see, the Great Pie War has escalated from Smart Pies to Smarter Pies to SMARTEST PIES - giant, state-of-the-art, satellite-guided pies.

POP! SPLAT! Will the war reach its messy conclusion in time for Feather and the other Muses to help Emma? Or will the trickster Muse Kokopelli sabotage everything?
