Four of the popular girls from school are finding that grown-up life isn't quite living up to their expectations - even though they have all achieved a measure of success in their roles as, for example, trophy wife or social media influencer.

So when they are contacted by an old schoolmate, Poppy Greer, who is now a successful doctor (and clearly has quite a lot of money), they happily agree to attend her hen party at a secluded island retreat. The thing is, they have no idea just how remote this place is - and what's going to come crawling out of the woodwork on this carefully planned, heavily alcohol-lubricated occasion.

It's hard to understand really why these four women would agree to attend Poppy Greer's hen do when they bullied her so much at school. Then again, people can justify and "forget'" some pretty bad behaviour, so perhaps their greed for a free, five-star hotel holiday experience overcame the need to ask such mundane questions? None of the quartet are in the least likeable, so you just know that karma is waiting in the wings...

This book is a fun beach read, but not entirely unpredictable. It also takes a while to get to the meat of the story, and the mean girls are all pretty obnoxious. But as revenge thrillers go, it's still entertaining. So, with a slight suspension of disbelief, you can allow yourself a few hours of escapist enjoyment.
