The shocking edge-of-your-seat thriller you won't want to miss. A tired old seaside town hiding a series of unsolved arson attacks. A derelict mansion in the woods with a long-buried secret. A bundle of old love letters that mask a dark story.

When Jamie's documentary investigation gets too close to uncovering the truth behind a series of deadly arson attacks that tormented Abbeywick in the 1980s, her family might be the ones who pay the price.

But for her younger sister, Cleo, the secrets that Jamie uncovers have the potential to get exactly what Cleo wants: to remove her mother's toxic new husband from their lives--forever.

All it takes is one spark to send everything up in smoke.
