A stranger saved her life. Two years later, she can't stop seeing his face. When Jo Calloway's car goes off an icy road outside Tanager Falls, Maine, a passing stranger pulls her from the wreckage and waits with her until help arrives. She thanks him the way anyone would - a card in the mail, a debt she assumes is settled. It isn't. Six months later, she runs into him again. Then again. Each time, there's a perfectly good explanation - his job as an insurance adjuster covers six counties; the world, especially this corner of it, is smaller than she thinks.
But when Jo spots him two rows behind her at the community theatre for the second year in a row, she starts keeping count. And the numbers don't add up to coincidence anymore. What follows is a slow, mounting reckoning: a detective who believes her but can't yet act, a sister who wants her to be wrong, a best friend who goes quiet with fear, and another woman - one county over, one accident earlier - who already knows exactly how this story goes if no one stops it in time.
Small Mercies is a psychological thriller about the debts we think we owe strangers, the instincts we're taught to doubt, and the particular horror of a threat that never once breaks the law. Perfect for readers who loved The Push, Verity, and The Silent Patient - and for anyone who has ever thanked someone a little too quickly, without asking what that gratitude might cost.
