ONE PERFECT HOLIDAY. ONE SHOCKING ENDING.

When Rob decides the family needs to get away for the summer Jess is not convinced - won't all the things they're escaping be waiting for them on their return? But the kids are thrilled, and before long their idyllic little cottage, the sea air, and the feel of skin sticky from sun-cream, lollies and sand, begins to work its magic. Jess allows herself to sink into the holiday vibes - the family even make holiday friends.

The summer heat intensifies Jess - ever vigilant - unearths a secret, a problem she's sure she can help solve. But things are not always as they seem. The water may look inviting but even the gentlest looking waves can hide the deadliest undercurrents.

As autumn approaches, Jess - and the reader - will come to realise this is going to end in a way no-one could have imagined...
