An FBI agent is pulled in two directions by the urgent case of a missing teenager, and the rapidly approaching death of her father, who alone holds a secret from her own dark adolescence.

Elsa Myers was damaged long before she started working for the FBI.  She lives alone in Brooklyn and is devoted to her work, above all else.  But with each new child that goes missing, memories twitch awake with things she’d rather forget about her own childhood.

Now, as she watches her father dying in the hospital, she’s forced to come to terms with grief and subverted rage associated with her past.  At the same time, she’s called into the case of a missing teenage girl, Ruby, and discovers the possibility that Ruby’s disappearance may not be an isolated event.  Newly partnered with NYPD Detective Lex Cole, Elsa throws herself into the investigation while unwelcome memories flood in.  But what feel like personal distractions ultimately inform the hunt for a criminal who won’t stop until he’s caught.  With Lex Cole’s help and the support of their growing friendship, Elsa navigates her inner minefield and perseveres as clues merge with instinct and together the investigators draw closer to their target.

As pressure mounts—the calls from the hospital, a media storm around Ruby’s abduction, and then a crisis involving Elsa’s beloved niece—self-destructive forces emanating from a dark secret from Elsa’s own past threaten to undermine her with potentially devastating consequences.
