The sixth installment of the Anomaly Archive series.

Haunted by the trauma of a mass shooting, Ellie McKinley has been a prisoner in her own home for a year, trapped by crippling agoraphobia and PTSD. Her sanctuary is a cage of her own making, a place she believes is safe from a world that has already taken too much.

But when a terrifying home invasion shatters her fragile peace, she discovers the greatest threat isn't outside.

Is she truly losing her mind, or is the creature she fears all too real?
