Dark Places by Gillian Flynn- excellent, well-written contemp literary fiction. About a woman who survives the murder of her mother and sisters, for which her brother, the sole other survivor, was imprisoned for committing. Events happen that have her doubting his guilt. Action jumps between her present-day investigations and flashbacks to That Fateful Day
Rebecca by Daphne du Maurier- an early-ish 'gothic.' Woman marries mysterious man and finds herself living in the shadow of his dead first wife Rebecca. But all is not as it seems
I totally didn't see it coming when I read the book, and when the 'big reveal' happened, I was surprised.
The Sparrow by Mary Doria Russell- while the UN debates how to handle first contact with an alien species, the Jesuits send a private ship. The sole survivor of the mission comes back crippled and traumatized. What went wrong? Great novel, goes back and forth between present day and flashbacks of what occured.
