Grace Reinhart Sachs has it all: husband who is a doctor, talented son, fabulous Manhattan apartment, and even a book deal.
Her book, You Should Have Known, is based upon a fairly simple premise. When you meet someone, he/she gives you many clues about his/her personality. What happens next in the relationship depends on whether one chooses to acknowledge those clues or ignore them. Based on the title of her book, Grace believes that many people ignore those clues.
The tables are turned on Grace when her pediatric oncologist husband, Jonathan, turns out to be a rather nefarious character. Grace, too, should have known.
This starts out a little slowly at first, but keep at it, reader! The story does pick up speed and improve considerably. Somewhat reminiscent of Gone Girl, but better.
