Two women are dead. They both look like you.

The giant stretch of frozen river was melting and the light made the lake glitter like crystals. The women lay side by side on the shore, eyes open and glassy. Their long, dark hair was like tangled rope, their faces a reflection of each other....

When two bodies are found dumped in a vast lake in Lakemore, Washington, Detective Mackenzie Price is first on the scene. She identifies one of the victims as Katy Becker, a local known for her work helping the community. The other victim looks strikingly similar.

Still grappling with a shocking revelation from her past, Mack is only too happy to throw herself into the case. But when she goes to break the news to Katy’s husband, the investigation takes an unexpected turn: Katy is very much alive and has never met the women who resemble her so closely.

Now the race is on to find the killer before Katy becomes the next victim. But when Mack unearths a disturbing connection to a 16-year-old suicide, she realizes they could be hunting someone whose crimes span decades - and there are more lives than just Katy’s at stake.

Addictive, pulse-pounding, and packed full of jaw-dropping twists, fans of Lisa Regan, Angela Marsons, and Karin Slaughter will love the Their Frozen Graves.
