I have not read this author before, but it had good reviews, so I gave it a go.
It's about this old woman on an airliner who goes into a funny trance and starts wandering up the aisles, predicting each passenger's year and cause of death. The author keeps you wondering whether the old lady really is clairvoyant. The thing is some of the passengers she predicts an early death for are sympathetic characters who you don't want to die. I wondered whether the author was going to paint herself into a corner, but I think she just about got away with it.
