When lonely single mum Janey stumbles into an art workshop, she can't believe her eyes when her left hand mysteriously scribbles a picture of two little girls and a strange message from someone called 'Hattie': Janey's childhood best friend. But they lost touch after Hattie's family suddenly moved away in mysterious circumstances. Janey's instincts tell her that she must finally find out what happened to Hattie, but life is already complicated enough: she's struggling with motherhood, a custody battle over her toddler son Pip is looming, and she finds herself falling for intense art tutor Steve. And when writing appears on the walls of her flat and Pip starts playing with an invisible friend, Janey fears she's losing her mind. Is it really a good idea to go digging up the past? As dark secrets come to light, she can't be sure what's real any more - or who to trust... Moving and suspenseful, The Last Day I Saw Her is a richly emotive story of friendship lost and found, and how facing up to the past can help you find a better future.
