dp books announces If I Were You, a new psychological thriller by Helen Matthews

London, January 2026 – dp books is proud to announce the publication of If I Were You, a gripping all-new standalone psychological thriller by Helen Matthews, now available for pre-order. Dark, emotionally charged and sharply observed, this compelling novel explores sisterhood, manipulation, and the terrifying consequences of believing the wrong person.

When Tessa, reclusive and struggling with long Covid and depression, is unexpectedly reunited with her estranged younger sister Maddie, she is drawn into a crisis she never anticipated. But Maddie’s account is riddled with inconsistencies. As flashbacks surface and unsettling details emerge, Tessa begins to question what is real and what has been carefully constructed. When Maddie vanishes, leaving her baby behind, Tessa is forced to confront a devastating possibility: that the truth she’s been told may place them all in terrible danger.

Taut, unsettling, and impossible to put down, If I Were You is a standout psychological thriller that asks how well we can ever truly know the people we love — and how far loyalty can stretch before it breaks. A brand-new frontlist title from award-winning author Helen Matthews, the novel reflects her fascination with the darker side of human nature and how a life can change in an instant. Matthews is the author of four published novels, with previous work winning awards including the Opening Pages of a Novel Award at Winchester Writers’ Festival and the Suspense & Thriller Prize in the 2022 PageTurner Book Awards.

If I Were You by Helen Matthews is now available for pre-order on Amazon and Kindle Unlimited. Official release is set for 5th February 2026. We can't wait for you to dive in.
