Detective John Mathers must discover the identity of a social media influencer, Ella, who is driving vulnerable teenage girls to suicide, before his own daughter, Dawn, becomes their next victim. In a world where beauty is idolised, Ella offers the girls the chance to be as beautiful as she is; to preserve their youth and looks forever by becoming one of her ‘chosen angels’. Dawn is a shy, withdrawn girl who Mathers has sworn to protect since the death of her mother and who he does not want to see age a day. As he enters the girls’ online world, Mathers finds Dawn’s profile; a profile of a girl strikingly different to the impressionable innocent who hides in her room. He soon learns that to discover Ella’s real identity he must discover Dawn’s real identity. When the truth of Ella’s identity is finally revealed it will reveal with it a deeper truth of his own identity, and that of the daughter and life he thought he knew.
