Sara’s Pick: Dead Woman Walking by Sharon Bolton
Enjoying a hot-air balloon ride, the passengers are inadvertent witnesses to a murder. The murderer, realizing that at least one of them has seen his face, follows them, waiting for the balloon to crash so he can finish them all off. Unexpectedly there is one survivor. She is now on the run, hiding from her assassin and not trusting the police. Wonderful twists all along especially at the end.
