"Dueling narratives propel this stunning psychological suspense...Hitchcock fans won't want to miss this nuanced, multilayered novel."—Publishers Weekly

A captivating tour de force untangling trauma, memory, and the justice we serve when everyone else has turned a blind eye.

Good girls keep quiet. But quiet girls can't stay silent forever—and the consequences are sure to make some noise.

When Alex arrives in Provincetown to patch things up with his new wife, Mina, he finds an empty wine glass in the sink, her wedding ring on the desk, and a string of questions in her wake. The police believe that Mina, a successful romance author, simply left, their marriage crumbling before it truly began.

But what Alex finds in their empty cottage points him toward a different reality: Mina has always carried a secret. And now she's disappeared.

In his hunt for the truth, Alex comes across Layla, a young woman with information to share, who may hold the key to everything his wife has kept hidden. A strange, quiet girl whose missing memories may break them all.

To find his missing wife, Alex must face what Layla has forgotten. And the consequences are anything but quiet.

In her debut thriller, S.F. Kosa presents a tightly-woven book sure to inspire questions about trauma, memory, and how well we ever know the people we love.

"Prepare to be enthralled—The Quiet Girl will grab your emotions and then hang on with a death grip. Atmospheric and twisty enough to deliver whiplash, S.F Kosa writes with a keen eye for detail and surprise endings. A compelling narrative that hums with momentum long after the reader is done."—Maureen Joyce Connolly, author of Little Lovely Things
