Before I Go To Sleep by S. J. Watson

Memories define us. But what if you lost yours every time you fell asleep? Your name, your identity, your past—everything, forgotten overnight. And the one person you trust may be hiding the truth.

Welcome to Christine’s life.

Every morning, Christine wakes up in an unfamiliar bed, beside a stranger she doesn’t recognize. A middle-aged face in the bathroom mirror is a stranger too. And every morning, the man beside her patiently tells her that he’s Ben, her husband, and that she is forty-seven years old—an accident years ago left her unable to remember anything overnight.

To fill the gaps, Christine relies on a handful of photos, a whiteboard in the kitchen, and a hidden journal. The journal, she’s told, is where she records daily events, with the help of Dr. Ed Nash, a neurologist treating her without Ben’s knowledge. As Christine writes in the journal, she pieces together fragments of her life—sessions with Dr. Nash, snippets of conversations with Ben, fleeting glimpses of her former self.

But as the journal’s pages accumulate, Christine begins to notice inconsistencies that don’t add up, raising troubling questions. As she unravels the mysteries of her own life, the truth she uncovers is more terrifying—and more dangerous—than she ever imagined.
