They were best friends forever. Then Kate made one little mistake…

Kate thought the spreadsheet was harmless—a private ranking of her four best friends detailing their various strengths and weaknesses. But when it leaks online and goes viral, her carefully curated life implodes.

Social invitations vanish, her business crumbles, even her marriage starts to fall apart. It’s as if the silken thread that has been holding everything together has been pulled and now it’s all unravelling.

And it gets worse. Someone on the list seems to be out for revenge, determined to destroy whatever is left of Kate’s perfect life. As anonymous threats multiply and her son falls mysteriously ill, Kate doesn’t know where to turn or who to trust.

Then, as the fallout from the list turns deadly, she finally understands that her one little mistake could cost her everything – including her life.

One Little Mistake - the chilling psychological thriller from the best-selling author of The Visitors and Make Her Pay.
