Palo Duro Canyon - nicknamed "the Grand Canyon of Texas" - is the second-largest canyon in the United States and the largest state park in the Texas panhandle. Once home to many Native American tribes, though long gone, traces of their civilization can still be found in the canyon to this day.

Rachel Hernandez, an anthropology student at West Texas A&M University has discovered something that hasn't been seen in nearly two hundred years: in the depths of Palo Duro, a fabled cave full of Native American carvings and paintings. Shortly after her discovery, she vanishes without a trace, the only evidence left behind is her bootprints in the trail that leads to the caves. Rachel's twin brother Ricky and her best friend Jordan seek answers in her disappearance, and what they find may be the biggest cover-up in all of history.

Returning to young adult adventure and mystery, #1 Amazon bestselling author Andrew J Brandt brings an intriguing story of things lost...and things found.
