When Paige Patterson travels to Arizona to spend the summer with her archeologist father, she expects answers. Why did her parents divorce? Why did her father choose his career over family? She doesn’t expect to be reunited with her best friend Emily Linton, or to find herself falling for the project manager’s son, Jalen Yazzi.

But the summer takes a terrible turn when Emily vanishes. As the police struggle for answers, Paige sets out to find the truth.

The search takes Paige from the Cliffside ruins of prehistoric Native Americans to the Navajo Nation to the horrifying possibility that the answer is much closer to home. Emily, it turns out, was not the only one good at hiding things.

Her father has no alibi for the night Emily disappeared. An intern with the motive insists he’s innocent. And Jalen has some secrets of his own.

Old bones might not be the only things buried in the ruins. As Paige digs deeper into Emily’s disappearance, she realizes that uncovering the truth may cost her everything – even her life.
