On a cool October morning, Lauren Wilder is shaken when she comes close to striking Bo Laughlin with her car as heâ€™s walking along the roadâ€™s edge. A young man well known in their small town of Hardys Walk, Texas, Bo seems fine, even if Laurenâ€™s intuition says otherwise. Since the accident two years ago that left her brain in a fragile state, she canâ€™t trust her own instinctsâ€”and neither can her family. Then Bo vanishes, and as the search for him ensues, the police question whether sheâ€™s responsible. Lauren is terrified, not of what she remembers but of what she doesnâ€™t.
Unable to trust herself and unwilling to trust anyone else, Lauren begins her own investigation into the mystery of Boâ€™s disappearance. But the truth can prove to be as shocking as any lie, and as Lauren exposes each one, from her family, from her friends, she isnâ€™t the only one who will face heart-stopping repercussions.
