You should have known
(Book)

Grace Reinhart Sachs is living the only life she ever wanted for herself: devoted to her husband, a pediatric oncologist at a major cancer hospital; their young son Henry, and the patients she sees in her therapy practice; she lives in the very New York apartment in which she was raised, and sends Henry to the school she herself once attended. She authors a book, You Should Have Known, in which she cautions women to really hear what men are trying to tell them. But weeks before the book is published a violent death, a missing husband, and an ongoing chain of terrible revelations force Grace to dismantle one life and create another for her child and herself.
