Josie Robinson, 18 years old, is ready for her first great adventure after high school—an internship with an airlines group. Wherever Josie goes, mysteries and fun seem to follow. Josie plans on writing to her younger siblings Becky and Charlie every day during her internship, as well as to her parents in Santa Fe, New Mexico. She often corresponds with her favorite high school teacher and her grandparents in Chicago, Illinois, where she grew up. She is ready for exciting things to happen, but because of her attraction to mysteries, she might end up with more adventure than she ever imagined!
