One loving couple. One surprise guest. One week to destroy everything....

This holiday is the first time my husband, Jeff, and I have been on our own in years, and I want it to be a fresh start. We can walk along the beach, eat ice cream in the bright Spanish sun, and fall in love again.

Then I run into Coco, the girl we all wanted to be at university. She’s just like I remember: effortlessly cool with her blonde hair and her white linen dress. I can’t resist inviting her round to our clifftop villa with its pristine pool, to show off how much Jeff and I have changed.

But when Coco steps from the dusty street into the cool tiled hall, her face freezes in horror. I turn to see Jeff, his eyes wide, his cheeks pale.

They pretend nothing’s wrong, but I know they’re both lying. And when I catch them in whispered conversations, I’m determined to find out what they’re hiding.

But when I confront them, the truth is worse than I could have dreamed.

And when things fall apart, not all of us will walk away....

From the best-selling author S.E. Lynes comes a brilliantly gripping thriller that will have you gasping out loud at the twists. Fans of Paula Hawkins, Lisa Jewell, and Gillian Flynn will love The Summer Holiday.
