When a woman is murdered by her husband, the seaside town of Adtoft unwittingly gains an angel. Invisible to all, she becomes a serial observer, but in death could Angel finally find a way to live? Neither dead nor alive, Angel is trapped in a solitary afterlife with nothing but her regrets and the rules of 'the glitch' to guide her. Yearning for purpose, Angel watches the residents of her seaside hometown-including an artist who quietly paints on the beach every day, a handsome paramedic, and her father who is stuck in a loveless marriage-while trying to avoid reminders of her murderous husband.Distracted by her daily observations, time passes in relative peace until a boy falls from the Ferris wheel and does what no one has done in years-sees her. Struck by the brief connection, Angel's tranquillity is overturned, causing her to seek those in peril as she searches for meaning in existing between life and death.
