Emma Walsh has finally worked up the courage to confront her husband James about his drinking—his alcoholic rages, his blackouts, and the fear his behavior has created for her and their two kids. But James never shows up to meet her as planned, and all her righteous words go unsaid. And unsaid they remain, because the next time Emma sees James, his body lies crumpled amidst the wreckage of his flashy car, which has been smashed to its final resting place halfway through the back wall of their suburban house’s roomy garage.

In the aftermath of the fatal crash, Emma and her teenage children begin to embrace life without James’s looming, volcanic presence. Buoyed by the support of her two closest friends, she struggles to deal with her grief, complicated by the knowledge that her husband’s legacy as an upstanding business owner and family man shines only because so many people, for so long, were so willing to keep his secrets—secrets that twist into new and unexpected shapes as the mysterious details of his last day of life begin to come to light.
