The Flight Attendant (TV Tie-In) by Chris Bohjalian

The Flight Attendant is a powerful story about the ways an entire life can change in one night. Cassandra Bowden, a flight attendant, wakes up in the wrong hotel, the wrong bed, with a dead man, and no idea what happened. Afraid to call the police, Cassie begins to lie. She lies all the way from Dubai to Paris. She lies to the FBI agents who meet her at the gate. Soon it's too late to face the truth about what really happened. A spellbinding tale of memory, alcohol, addiction, and murder.
