THE MATHEMATICS OF LEAVING QUIETLY

Mara Ellison believes that nothing ends without warning.An actuary by profession and by instinct, she has built her life around a simple conviction: if you pay close enough attention, every catastrophe announces itself in advance.Then her sister's marriage ends without explanation.Looking for the signs everyone else missed, Mara begins recording the smallest changes between two people the delayed messages, the separate purchases, the objects that slowly migrate to opposite sides of a room. What begins as an attempt to understand one failed marriage becomes something far more unsettling: a mathematical model capable of estimating when a relationship is already on its way toward ending.And then Mara makes the mistake of applying it to her own life.As ordinary gestures become evidence and silence becomes data, she must confront a question no equation can answer: if you knew exactly when someone was going to leave, would that knowledge save the relationship or destroy it first?A novel about love, certainty, and the dangerous distance between understanding a life and actually living it.
