New York Times bestselling author Mary Kubica published her latest novel, It's Not Her, on February 3, 2026, through HarperCollins — and within weeks the book had attracted a screen adaptation deal. According to Deadline, production company Gaumont has acquired the rights to the newly published suspense novel for TV series development, marking a swift move from page to potential screen for Kubica's latest work.
The Book and Its Publisher
It's Not Her is a standalone thriller centred on a deadly family vacation mystery, published by HarperCollins. People magazine first revealed the cover and announced the title, describing the novel as a "nail-biting journey" for fans of the genre. An excerpt is available to read via book-mojo.com, which noted the book went live on its publication date. For a critical assessment of Kubica's craft as demonstrated in an earlier work, see our review of Every Last Lie.
Gaumont's Acquisition and Who's Involved
The TV rights deal, reported by Deadline, positions Gaumont — the French-founded international production and distribution company with an active slate of English-language television — as the driving force behind any adaptation. No network or streaming partner has been named in the sources at this stage. Kubica herself is a New York Times bestselling author whose work has previously drawn significant trade and retail attention; her publisher's news page lists It's Not Her alongside her back catalogue, which includes She's Not Sorry and The Good Girl.
Context: Kubica's Place in Domestic Suspense
Kubica has built her profile in the domestic suspense genre across multiple novels. Her official site documents a track record of trade recognition stretching back to her debut, The Good Girl, which earned a Midwest Connections Pick and coverage in Library Journal's mystery preview. Her 2017 novel Every Last Lie — which follows a young mother investigating the circumstances of her husband's fatal car accident through alternating timelines — is described on Kubica's site as exploring "the dark recesses of a mind plagued" by grief and deception, illustrating the structural and thematic approach she has carried through her subsequent work. The rapid optioning of It's Not Her continues a pattern in which psychological thriller novels with strong commercial profiles attract screen interest shortly after publication.
What to Watch
The Gaumont TV development deal is in its early stages, with no production timeline, casting, or network attachment confirmed in available sources. Kubica is also conducting promotional events around the release; Adventures by the Book has listed a San Diego appearance welcoming her back as a returning guest author. Readers and industry observers tracking the project's progression can follow updates through Deadline's entertainment coverage and Kubica's official news page.
