The Sister: Discover the unputdownable psychological thriller from #1, MILLION-COPY BESTSELLER Valerie Keogh

You’d trust your sister with your life—wouldn’t you? 👀

Twin sisters Ellie and Tia were torn apart the day their parents died. Ellie was given the picture-perfect life—marriage, a home, security. Tia was cast aside, growing up in the shadows, unwanted, unloved, and never quite belonging.

Now, after years apart, fate brings them together again. Ellie is desperate to believe this is a chance to rebuild their bond. To finally have the sister she always longed for.

But Tia hasn’t come back to play happy families. She knows the secret Ellie is hiding— a secret that could shatter her perfect marriage and destroy everything she’s built.

Because Tia has been waiting her whole life for this moment. And she isn’t going to let Ellie escape the past—or the truth.

Another brilliant psych thriller from number one, million-copy bestselling author Valerie Keogh. Perfect for fans of Frieda McFadden, Lisa Jewell and Keri Beevis.
