A wife burning with resentment. A husband hiding the past. Their teenage daughter crusading for the truth. What if your search for the truth puts your family at risk?

The close-knit community of Kinton Bay is shocked when fifteen-year-old Siena Britton makes a grisly discovery in the national park. She believes it's a skull from the town's violent colonial past and posts a video which hits the news headlines.

Her parents, Meri and Rollo, aren't so sure. In 1998, their classmate went missing after a party in the Killing Cave. They're horrified to discover the destructive teenage parties are still happening, and Siena was there last weekend.

While Meri is trying to keep her daughter out of trouble, she doesn't realize her son, Taj, has his own problems. And none of them foresees the danger that Siena's actions will create for the whole family.

As more secrets are exposed, the police investigate whether multiple murders have been committed. If so, by whom? And is the killer still living in Kinton Bay?

The Liars is a heart-stopping cocktail of family secrets, sinister unsolved killings and a community at war with itself.

From the bestselling author of Six Minutes and The Good Teacher comes a compelling family drama of marital secrets and family tensions set within an investigation of sinister unsolved killings.
