A quiet evening in Cocoa Beach turns into a nightmare when FBI profiler Eva Rae Thomas's peaceful family night is shattered by a bloodcurdling cry from the garage.

Thirteen-year-old Elijah-Matt's estranged son-emerges from the shadows, terrified: his grandmother has been missing for days, her phone abandoned, and blood staining the closet floor.

Unwilling to trouble them, Elijah hid...until now.

Determined to find the truth, Eva Rae and Matt set out to uncover what really happened to the woman they thought they knew. Was she losing her grip on reality, or was someone hunting her?

Their questions explode into terror when Eva Rae discovers a second victim-a woman savagely murdered in her own home-and senses an impossible link between the two crimes.

When a woman collapses on Eva Rae's doorstep, battered and silent, the profiler realizes the stakes are deadlier than she ever imagined-and the answers lie buried in a decades-old secret.

As Eva Rae pieces together clues from the past, the killer closes in once more.

In a pulse-pounding showdown, long-buried traumas and twisted vengeance clash with a mother's fierce love and a family's fragile bonds.

Revenge is a shadow that reaches across generations. Justice, however, may demand the ultimate sacrifice.

Can Eva Rae save a grandmother, stop a killer, and keep her fractured family from falling apart? Or will the darkness claim them all?
