Mel and Dimi were only 16 when their world fell apart, and for the past 10 years, the young women have been pretending to themselves and everyone else that their mentor and role model, Sally, will be back any time now to resume control of the airport where they've been covering for her all this time. But when Bo Black unexpectedly arrives from Australia looking for Sally to exact vengeance for her theft of his father's hard-earned money and prized antique plane, the deception becomes more than the girls can handle. Especially when threatening notes and e-mails reveal that the deed to the airport is now in Bo's name, so that everything Mel and Dimi have worked so hard for is now in jeopardy.
