Like many thrillers, this book is based on the age-old issue: Whom do you trust?
Rachel and Clara go way back. And they both believe they know each other inside out. There's no secret that they don't know about one another: Rachel's absent father and her alcoholic hippy mother; Clara's departed mum and the strict father she lives with.
But...it turns out that there's quite a few things that they have kept from each other.
They met when Rachel was the new girl in class and Clara was the friend everyone wanted. Now in their late 20s, Rachel has everything, while Clara's life seems to be out of control.
The book is set in Brighton - always a joy to read - and the descriptions of the clubs and bars are done with an eye for detail. Who remembers The Zap?
Rachel is a crime reporter for a TV station and she is stunned when she finds out that she is about to report on a missing person. Her best friend, Clara. The girl who didn't turn up for a date in a bar the night before.
The nightmare continues when her boyfriend also goes missing. He's seen on CCTV with Clara. Rachel has to face some terrible truths in this page-turner of a book.
We all think we know everything there is to know about our nearest and dearest, but the truth is something that we are all guilty of hiding from.
