Olive Oh can't wait to spend a weekend camping with her best friend Marcus Wong and his family. They'll get to see stars, observe nature, and - best of all - get away from Olive's older siblings, whose bossy advice is driving her nuts. But a week of rainy weather threatens to cancel Olive's weekend plans. Will Olive be stuck at home with her crabby siblings? Or can she still find a way to save the day?
