Emma Walker wakes in a hospital seventeen days after a boating accident, missing five years of memory and unable to recognize the elegant surgeon who says he is her husband.

Back at their cliffside home near an old lighthouse, small contradictions pile up—an allergy she never had, a sister who doesn’t exist, roses she has always hated—and hidden letters in her own handwriting suggest she was planning to flee with her young daughter.

As fragments return, Emma realizes her amnesia may not be an accident at all, and that the child, the lighthouse, and a man from her forgotten past all hold pieces of who she really is.

Tropes: amnesia protagonist, gaslighting spouse, domestic captivity, fabricated marriage, unreliable reality, hidden true love, child as secret ally, evidence-gathering escape plan, sinister doctor/mad-scientist antagonist, is-she-crazy-or-is-it-real, forbidden love between brothers
