My baby girl. This morning she was so excited for school. I bought her new shoes last night. Pink, sparkly shoes. She loved them so much. She wore them for the first time today. And now she is gone....

It is every mother’s worst nightmare. Eight-year-old Kailey Richardson skips out of the school gates in her brand-new pink shoes and never makes it home. Between the school and the safety of her shiny red front door, someone has taken her.

Private Investigator Lucy Kendall sees the fliers of a smiling, gap-toothed Kailey and knows she won’t be able to sleep until the little girl is found. Having lost her own sister to the darkest evil, she is determined to help find Kailey before it is too late.

As Lucy talks to Kailey’s friends, desperate to find out who has taken the happy little girl, she begins to form a worrying picture of the days before Kailey’s disappearance. The blue car idling in the street outside the school. The friendly man across the road. And Kailey’s mother, Jenna, hollow-eyed and jumpy, clutching Kailey’s teddy bear and not telling Lucy everything.

Lucy has promised Jenna she will do everything to find her daughter. But then she discovers Jenna has a connection to the prime suspect in Kailey’s disappearance...and one that brings Lucy’s past rushing back to haunt her. Time is running out to find Kailey, but will Lucy be able to save this innocent little girl before her own demons destroy her?
