Seventeen-year-old Ava Sinclair just wanted one last connection to her late mother?a quiet girl with a love of photography and secrets buried in the attic. But when Ava discovers an antique camera labeled Tempus Fugit, her grief turns to terror. The photos it produces don't capture the present... they reveal the future.

At first, Ava doesn't believe what she's seeing?until the snapshots begin coming true: a car crash, a blood-soaked crime scene, a figure lurking behind her classmates. As the photos turn more disturbing, Ava's life spirals into danger. The camera once belonged to Emma Morrison, a girl who vanished fifteen years ago under mysterious circumstances. When Ava investigates Emma's disappearance, she uncovers a chilling truth: Emma was murdered for the camera?and the killer is still watching.

With the help of a haunted detective, a skeptical FBI agent, and a mentally ill eyewitness whose memories were dismissed for years, Ava races to uncover the identity of the murderer. But the deeper she digs, the more the camera consumes her?blurring the line between fate and free will, and placing her directly in the crosshairs of a serial killer obsessed with turning death into art.

As the killer closes in, Ava must make an impossible choice: destroy the camera and give up her power to protect others, or keep it and risk becoming the next photograph.
