When archaeologist Chuck Bender witnesses a shocking death while conducting a survey at Great Sand Dunes National Park in Colorado, local cops quickly declare the bizarre killing an accident. But when Chuck discovers a series of mysterious artifacts that threaten the lives of film students in the park—including his daughter Rosie—he will stop at nothing to uncover the truth.
Is a killer quietly stalking Great Sand Dunes? Are the students the next target? And why does no one seem to care about the young man whose brutal demise started it all? Together, Chuck and Rosie must unravel a devious web of deception and deceit—before one death turns into a massacre.
