A fresh, clever psychological thriller full of toxic characters you'll love to hate.

CLARE MACKINTOSH

Takes the ordinary and twists it until the sense of danger is utterly overwhelming. Tammy Cohen is rapidly becoming one of my favourite authors

EMMA KAVANAGH

A compelling tale of office politics and childhood trauma, that slices through the insecurities, jealousies and hidden agendas of the work place. Skilfully written with Cohen's trademark piercing observation and vivid imagination, this book will have you nervously watching your colleagues wondering what lies beneath their masks. With twists and turns and expertly ratcheted tension, it had me gripped from the off.

I was on the edge of my seat. Psychological thrillers don't get much better than this!

Tammy's books have a way of making you feel like something truly awful is just seconds away, and your whole body is tensed waiting for it. Dark and menacing you won't want to put this down until you know where the danger is coming from.
