It's Archie's favorite holiday—Diwali. And this year she gets to share it with her friends and introduce them to the festival of lights! Archana loves her family's annual Diwali (deh-vah-lee) party, and this year she gets to share it with all her friends from school. She helps with the decorations and the food, and is eager for everyone to arrive. But once the party starts a thunderstorm kicks up and drenches the outside decorations and knocks out the power. Archie worries that everything will be ruined. How can there be a festival of lights without any electricity?
