If you were to spy through a crack of their door or even look through the window for a few seconds, you’d see a perfectly functional family. However, if you peered inside for more than a few minutes, you could spot and feel the slightest tension among them, see the tired and resentful looks from Mom to Dad,  hear the sharp and demeaning retorts from Dad to Mom; if you were to enter their house and live in their world for a few 300 pages like Niederhoffer allows the reader to do, you would see the jealousy and secrets that threaten to tear Cass’ and Ryan’s marriage apart, the resentment and guilt boiling under the surface and something far more dangerous that will cause Cass, and the reader, to wonder if she is losing her mind.
