'SO witty, so entertaining, yet so moving. Countless women will identify with Laura Clark. I loved it so much!' MARIAN KEYES ------- Who is Laura Clark? To her colleagues, she's an invisible forty-something HR manager, emailing about lift repairs and quietly stocking the meeting-room snacks. To her golf-obsessed husband and selfie-obsessed teenage daughter, she's the reliable constant - dinner on the table, mess cleaned away, needs met without thanks. To her elderly mother, she's a patient ear for endless complaints. Laura Clark is the woman everyone relies on. And barely anyone sees. But one day Laura puts on her 'out of office' message - and doesn't come back.

And soon, everyone's formerly ordered lives quickly begin to descend into all-out chaos. Where has Laura gone? Has something terrible happened to her? Or has she - unthinkably - decided to finally give her own life the finger? To find out, the people in her life must realise that, maybe, they never really knew Laura Clark at all .
