The Last Flight by Julie Clark

Claire and Eva both have reasons for wanting to disappear, so when they happen upon each other at the airport, they decide to take the other person's flight. However, when one of the planes crashes, the danger they thought they were leaving isn't far behind. A great read-alike for The Last Mrs. Parrish by Liv Constantine, The Passenger by Lisa Lutz and Peter Swanson. It will be published in June.
