After learning the truth about his origin, Buck Reilly embarks on his greatest adventure yet, but one that threatens his very existence. The identity of the woman who gave him life, and her family history, have been fiercely protected in Scotland for generations, which puts Buck in the crosshairs of a secret society whose sole purpose is to prevent the truth from being exposed. Buck must quickly find missing ancient documents and a map to a hidden cache of treasure, or he and his friends will be killed.

The breathless pace will carry you into the wee hours as Buck races against the clock to overcome the double-cross that will cut him to the core, as he faces-off against the coldest, most brutal reality one could endure. The journey leads him to the ends of the earth, where no amount of treasure can overcome the deep treachery that lurks under the charcoal sky.
