Celestia has long been a master of the ancient art of making the perfect cup of tea. Luna, on the other hoof, follows the dark heresy of coffee. Caught between them is the newly-minted princess, Twilight Sparkle, who for some reason can't make a drinkable cup of tea no matter how hard she tries. Will Celestia be able to correct her errors and show her the way into the enlightenment of the true beverage, or will Luna win her over to the dark side at last?
