Stunning debut psychological thriller in the vein of Into the Darkest Corner and Sister.      A lingering, compulsive debut novel that will keep you tightly in its grip. What would you do if a young girl knocked on your door and asked for your help? If it was snowing and she was freezing cold, but you were afraid and alone? What would you do if you let her in, but couldn'’t make her leave? What if she told you terrible lies about someone you love, but the truth was even worse? Stella has been cocooned in her home for three years. Severely agoraphobic, she knows she is safe in the stark, isolated house she shares with her husband, Max. The traumatic memories of her final case as a psychologist are that much easier to keep at a distance, too. But the night that Blue arrives on her doorstep with her frightened eyes and sad stories, Stella’'s carefully controlled world begins to unravel around her.
