Nikki Boyd's flight into Nashville was routine—up until the crash landing at the airport. When the dust settles, Nikki discovers that the woman who had been seated next to her on the plane is missing—and no one will admit she was ever there. Erika Hamilton had been flying to Nashville with an air marshal as a key witness in an upcoming grand jury trial. When she flees from the crash, is she running from trouble or straight into it? Before Nikki can even see her family, she and her team are pulled into a missing persons case where the motives are as unclear as the suspects.
