«Reed's Beach» by Bret Lott

Hugh and Laura Walker could never have anticipated that the single greatest source of joy in their lives could so suddenly fill them with such unrelenting grief. The death of their only child, seven-year-old Michael – struck by a car just seconds after stepping off his school bus – has left them stranded in a sea of sorrow. With no emotional compass to guide them, the Walkers retreat to an old cottage near Cape May, New Jersey, where, separated from the daily reminders of their numbing loss, they hope to reenter the world of the living.
But lurking just below their sanity and resolve are memories – not only of the simple joy that Michael brought to their lives, but also of the horror of his fatal accident. Buffeted by the conflicting winds of mourning and renewal, the Walkers see the once-solid foundation of their marriage begin to loosen. And Laura harbors a secret – one essential to her self-preservation, but which could destroy all she and Hugh have ever been to each other. Reed's Beach weaves domestic tragedy with a strikingly original thriller of the heart, revealing the truths hidden deep within each of us, while holding out the elusive promise of love and hope.
