For years FBI Agent Emma Griffin was largely a lone wolf.
She insulated herself from the rest of the world. With very few exceptions.
Now, that has all changed. Opening herself has given her a chosen family she loves.

Working with her cousin Dean has always made her happy, and now she can help someone find a piece of their family that disappeared years ago.
An FBI agent who went undercover and never surfaced.
As they dig deeper into his disappearance, they find a potential connection of that case with the mystery of the 3 girls.
But as bodies connected to the case turn up in odd locations.
Emma struggles to make sense of what happened the night of their last sleepover.
