Once you’ve read her private diary, can you ever hope to earn her trust? 

Engineering grad student Chayce Wagner lives by logic and order. But his carefully structured world is upended when he finds a nameless diary tucked into the seat pocket of his Delta flight. Every handwritten page pulls him deeper. It discloses a normal, happy life shattered by secret sins and fears; one that seems destined for destruction. Chayce is determined to find and rescue the woman behind the ink.

Esteffi Avila is a ghost by necessity; anonymity is her one hope for survival. She erased her identity and fled her home to escape a cartel hunting for the fortune her parents embezzled. Her diaries are the last pieces of her former soul. Losing the latest one on a plane feels like a death sentence.

As the killers close in, her biggest threat might not be the men with the guns, but the stranger who is committed to becoming her savior.

Her Lost Diary is romantic suspense that is part cartel thriller, part contemporary romance: think Sicario meets You’ve Got Mail.

The story is crafted for fans of slow-burn emotional tension, ever-present danger, and the uniquely intimate character studies flowing from a diary-centered narrative.

This is a novel built for the BookTok and Bookstagram communities, and traditional book clubs, who appreciate a morally complex heroine, high-stakes storylines, and slow-burn payoffs.

It’s best consumed in long, greedy sittings; the kind where you keep promising yourself just one more chapter. You’ll be immersed in a life in hiding, and feel the deep discomfort—yet exhilaration—of being intimately understood by a stranger.
