Claire Cook has a reason to run. She has an abusive, powerful husband and she's worked very hard to get away.
Eva thinks she has a reason to run. She's been making a very good living doing a not great job (don't want to spoil). She becomes a target of someone she has trusted.
They meet in the airport and decide to swap flights. One of their planes goes down.

This was a fast paced, dual POV told story. I read half for a buddy read and made myself stop to talk about the first half. I them picked up the book after talking and finished. I just had to know what happened! I really enjoyed Claire's POV the most, Eva there were certain problems I had with her and her decisions. But highly enjoyable!
