Mia is a young woman with a sad past who has now ingratiated herself into the family of her missing coworker, Celeste. What they don't know is that Mia made an impulsive decision that might have cost Celeste her life. She ran into a group of other preschool teachers having a night out at a local pub. They halfheartedly asked her to join them but she declined. When they walked away, she found Celeste had dropped her keys. Rather than hand them over, she stuck them in her purse, getting back at the women who had once again left her out. But the next day, Celeste is reported missing, having never made it home. Mia can't believe it - she just knows that if she'd given Celeste her keys back, she wouldn't have disappeared. So she throws herself into the search, befriending Celeste's family and investigating any new lead she discovers.

While doing so, she's convinced that someone does not want her involved with this family, and she reports each new threat to the detective in charge. But because of her past, he thinks Mia is trying to use Celeste's disappearance as a way to put herself in the spotlight. Her mother vanished after locking six year old Mia in a shed. Her mother's boyfriend didn't know of her existence and when her mother never came back to get her, Mia had to literally dig her way out into the surrounding forest. She realizes now that her mother's case never got close to the publicity that Celeste's has. While she does want it looked into, she swears that she's not making anything up - someone really is following and threatening her. Is it worth divulging the truth about the keys to get the detective to take her seriously? That would surely alienate her from Celeste's family, who she feels truly care about her, a surrogate family for the one she never had. She must decide quickly, before she's the next one to disappear.

This was a good story, I didn't see the end coming which is always a pleasant surprise. Some things felt a bit off, like her lack of friends - just because she's timid and has anxiety? No one appears to outright dislike her, so it seems odd she'd be left out. And the dialogue between her and the detective is downright weird sometimes, sounding straight out of the pages of a 1940s crime magazine. She goes from anxious to ballsy too quickly for me, fluctuating back and forth throughout the story. A little disjointed, but an overall engrossing tale.
