The Last Flight by Julie Clark

Claire is running from her life and an abusive wealthy husband. Eva is running away from mistakes. When they meet at the airport it only seems the perfect solution is to swap plane tickets. A plane crash killing all survivors on its way to Puerto Rico makes the world aware that Claire is dead but really she is in California assuming Eve's identity. She is leaving one set of problems for another. In a world of female driven thrillers this is one plot I don't think we have seen reworked a dozen times. Clever and full of unexpected twists, this is a thriller for readers who love smart women exacting justice.  4 stars for a great summer thriller.
