Professor Skye McAlister never dreamed archaeology could be so dangerous. But discovering a mysterious artifact in the Scottish Highlands has somehow landed her in more trouble than she can handle. It seems a secret society has taken an interest in her work of deciphering the lost language of the ancient Pict civilization, and it may just cost Skye her life.
When a hunky FBI agent shows up, things get even more intense as he enlists the help of Skye and her team to crack the case that has stumped the bureau's finest for decades. The investigation takes them on a chase through medieval European history and may help Skye find answers to even deeper questions about who she really is.
